WFDF Official Rules of Flying Disc Sports
Article VI - Field Events
Copyright (c) 1994, WFDF
Last Change: 20 Jul 1994
Comment: Field events is a general term used to classify
individual disc sport events, namely: accuracy, distance, maximum time
aloft (hereinafter referred to as "MTA"), throw, run and catch
(hereinafter referred to as "TRC"), and self-caught flight
(hereinafter referred to as "SCF"). The common link among the field
events is the competitive measurement of a particular basic skill.
Accuracy measures a player's ability to consistently throw a disc
through a specified target. Distance measures how far a player can
throw a disc. MTA measures the length of time a player's throw is in
the air. TRC measures the distance a player can throw a disc and catch
the throw, prior to the throw hitting the ground, and SCF combines the
events of MTA and TRC.
Outline of Contents
601. Field of Play
- 601.01. General:
- The playing field for field events may have any surface, although
well-trimmed grass is suggested, which is essentially flat, free of
obstructions and/or holes, and affords reasonable player safety.
- 601.02. Obstructions:
- If there are permanent and predictable obstacles which may affect
the completion of a throw, throwing sites should be located to
minimize potential problems. Once these obstructions have been noted
by the head or site judge, however, no re-throw will be granted if the
obstructions come into play. Designated spectator areas shall be
considered an obstruction.
- 601.03. Accuracy:
- The playing area in accuracy shall consist of seven throwing
stations, set at varying distances and angles from the target; said
stations being clearly marked by foul lines which consist of a front
line and perpendicular sidelines, both of which are 120 cm in length
and between 5 cm and 10 cm in width. Small, flexible cones should be
used to mark the front corners. The location of the throwing stations
is determined by the target itself and the lateral extension of its
plane. See Figures 6.1 and 6.2.
- A. Straight-Ahead Throwing Stations:
- There are three straight-ahead throwing stations, with respective
distances of 13.5 m, 22.5 m, and 31.5 m from the target. The midpoint
of these stations shall be on the imaginary line that makes a
perpendicular intersection of the target plane at the midpoint of the
target.
- B. Left-Angle Stations:
- There are two left-angle stations which are located to the
player's left of the target; one station 13.5 m from the target and at
an angle to the target such that a line drawn from the midpoint of the
front foul line of the station and intersecting the target plane at a
perpendicular angle will be 4.5 m in length; and one station located
22.5 m from the target along the same angle as the 4.5 m line, such
that a line drawn from the midpoint of the front foul line of the
station and intersecting the target plane at a perpendicular angle
shall be 7.5 m in length.
- C. Right-Angle Stations:
- There are two right-angle stations which are located to the
player's right of the target; one station 13.5 m from the target and
at an angle to the target such that a line drawn from the midpoint of
the front foul line of the station and intersecting the target plane
at a perpendicular angle will be 4.5 m in length; and one station
located 22.5 m from the target along the same angle as the 4.5 m line,
such that a line drawn from the midpoint of the front foul line of the
station and intersecting the target plane at a perpendicular angle
shall be 7.5 m in length.
- D. Optional Field of Play:
- The playing area may also use a moveable target to create the
correct angle stations. Positioning for the target should be painted
on the ground. See Figure 6.3.
- 601.04. Distance:
- The playing area in distance shall be of sufficient size to permit
the entire course of the disc flights to be contained within its
perimeter, as level as possible to insure an accurate measurement, and
in an area which permits an unblocked windflow. The layout of the
field shall be such that throws may be made with the prevailing wind.
There shall be five throwing sites, each marked with foul lines which
consist of a 3 m front line and perpendicular sidelines which are 3 m
to 15 m in length. These lines shall be between 5 cm and 10 cm in
width. Small, flexible cones should be used to mark the front corners
of each site. At least 6 m of additional space shall be provided
between each throwing site. See Figure 6.4.
- 601.05. MTA:
- The field for MTA shall be of sufficient size to permit the entire
course of the disc flights to be contained within its perimeter, and
as level as possible to facilitate player movement. No field markings
or other delineations or designations shall be required.
- 601.06. TRC:
- The field for TRC shall be of sufficient size to permit the entire
course of the disc flights to be contained within its perimeter, and
as level as possible to facilitate player movement. Depending on the
field size and wind direction, one or more foul circles shall be
clearly marked by painted lines measuring 4 m in inside diameter. The
lines shall be between 5 cm and 10 cm in width. See Figure 6.5.
602. Equipment
- 602.01. Discs:
- A player may use one or more of any type of flying disc, so long
as they meet the minimum requirements set forth in Article I of the WFDF rules and the specific
requirements for accuracy in paragraph
602.01(A). The discs need not be identical.
- A. Special Restrictions:
- For game design and safety considerations, discs in accuracy play
must meet both the W.F.D.F. general disc specifications (section 107) and these additional specifications:
- (1) Rim configuration:
- must achieve a rim configuration rating of 75 or greater (may not
be bevelled - see section 108 [D]).
- (2) Leading edge radius:
- must have a leading edge radius that is greater than 1/16 in (1.6
mm) (see section 108[E]).
- (3) Weight:
- must weigh no more than 6.7 gm per cm of outside diameter.
- (4) Rigidity:
- must be sufficiently flexible to bend to the point of buckling
when subjected to no more than 9.1 kg (20 lb) of weight in a standard
testing procedure (see section 108 [F]).
- 602.02. Measuring:
- For distance and TRC, either tape measures or electronic measuring
devices with the ability to measure throws to the cm up to 200 m in
length, shall be provided.
- 602.03. Stopwatches:
- For MTA, four stopwatches with the ability to measure time to
one-hundredth of a second shall be provided.
- 602.04. Field Target:
- In accuracy, a field target shall be provided which shall consist
of a two - dimensional structure, made of non-flexible material,
presenting a square target with 1.5 m sides, the target area being set
1 m above the ground. The field target shall be constructed to be self
- supporting and have a light net attached to the rear. See Figure
6.6.
603. Rules of Play
- 603.01. Accuracy:
- A. Play:
- A player shall make four throws from each station for a total of
28 throws, with the objective to have as many throws as possible pass
through the target area. He shall complete all four throws at each
station before moving on to the next station. The stations may be
carried out in any order. No one may be positioned in or near the
target as a catcher, but someone may assist in retrieving thrown
discs.
- B. Discs:
- The player shall provide at least four of his own discs as per
section 602.01. It is advised that an
additional disc be available in the event of damage to one of the
discs.
- C. Time:
- A total of 7 minutes shall be allowed for completion of the 28
attempts. A time warning shall be given at 1 minute remaining. Any
throw which is released after the expiration of the 7 minute period
shall be deemed an unsuccessful throw.
- D. Foul:
- No supporting point of the player shall rest on or beyond the foul
lines or their extensions at the moment of his release. A
follow-through motion which crosses the foul line after the release is
permissable. Any foul shall count as an unsuccessful throw.
- E. Good Throw:
- A good throw shall be made whenever the thrown disc passes
entirely through the target plane from front to back and a foul or
time violation is not committed.
- F. Scoring:
- A good throw shall count as one point. An unsuccessful throw shall
receive no points.
- 603.02. Distance:
- A. Play:
- The player shall make five attempts in each round to throw a disc
as far as possible.
- B. Discs:
- The player shall provide at least 5 of his own discs as per
section 602.01. It is advised that an
additional disc be available in the event of a re-throw.
- C. Time:
- A player shall make all five of his throws within 2 1/2 minutes
from the time the signal is given by the line judge. A time warning
shall be given at 30 seconds remaining. In semi or final rounds, the
format may be changed to allow simultaneous time periods. Under this
format, players are given 4 minutes to make all five of their throws
from the time the signal is given by the line judge. All players throw
during the same time period. In semi play, two consecutive
simultaneous rounds may be used. A time warning shall be given at 2
minutes remaining and at 30 seconds remaining. Under either format,
any throw released after the expiration of the throwing time period
shall not be marked.
- D. Foul:
- No supporting point of a player shall rest on or beyond the foul
lines at the instant of his release. A follow-through motion which
crosses the foul line after the release is permissable. In the event
of a foul, the throw shall not be marked.
- E. Measurement:
- Legal throws shall be measured from the midpoint of the front foul
line to the center of the disc at its point of impact. All throws
shall be measured to the nearest cm.
- F. Score:
- The length of a player's longest throw, to the nearest centimeter,
shall be his score.
- G. Interference:
- In the event a throw is touched while in flight by a person or
animal, the player shall have the option of counting the throw and
having it measured from the point of interference, or immediately
choosing to take a rethrow. An additional 30 seconds will be granted
for each rethrow.
- 603.03. MTA:
- A. Play:
- A player shall attempt to throw the disc in such a fashion that
the disc remains airborne for as long as possible, before catching the
disc himself. Each player shall make five attempts in each round.
- B. Discs:
- A player shall provide at least one of his own discs as per
section 602.01. It is advised that an
additional disc be available in the event a disc is lost or becomes
unsuitable for use.
- C. Timing of the Throw:
- The timing of the flight of the throw shall be measured from the
instant of release until the instant the disc is initially touched in
the catching attempt. Time shall be calculated to the nearest
one-hundredth of a second. The player's time for a throw shall be the
median (middle) time rating of three time ratings received from the
measurement crew. In the event that only two times are recorded by the
measurement crew, the back-up timer's result shall be used as the
third rating. If no backup is available, the two ratings shall be
averaged. If only one valid time is available, a re-throw is
necessary. No time shall be recorded for unsuccessful throws.
- D. Time of Play:
- A player shall release a throw within 15 seconds after receiving a
signal to throw from the site judge. Any throw released after the
expiration of the 15 second period shall receive a score of zero.
- E. Catch:
- A catch shall be deemed valid when the throw is caught and
controlled in one hand by the player, without the disc simultaneously
touching any other part of the player's body and prior to the disc
touching the ground. The player is permitted to touch the disc an
unlimited number of times before the catch is made, as long as he only
touches the disc with one part of his body at a time. In the event the
disc touches the ground simultaneously with the instant the catch is
made, the catch shall be valid. A player shall be in full control of
the disc before he lets it go, changes hands, or touches the disc with
another part of the body for the catch to be valid. The validity of
questionable catches shall be announced by the player, subject to
review by the event judges.
- F. Score:
- The player's score shall be the single best time recorded.
- G. Groupings:
- To facilitate rapid completion of the event, the players shall be
placed in groups of five for the purpose of alternating the order of
throws. Each player makes one throw, then the order is repeated until
each player has made his five throws in the round.
- H. Starting Order:
- In the first round the starting order is decided by some order of
random distribution. In all subsequent rounds, each player, in
descending order according to his performance in the previous round,
shall be given his choice of throwing order and site. If two or more
players have the same results in the previous round, the order of
choice in the current round shall be decided by the disc flipping
method. See section 104.03.
- I. Interference:
- Whenever a catchable throw in flight is touched by any person or
animal, or a player in pursuit of a catchable throw is impeded by
interference, the throw shall be declared void and the player shall
receive an additional attempt. Permanent and/or predictable
obstructions, as per section 601.02, shall not
entitle the player to another attempt.
- 603.04. TRC:
- A. Play:
- A player shall attempt to throw the disc from a marked circular
area in such a fashion that the disc travels as far as possible before
catching the disc himself. Each player shall make five attempts in
each round.
- B. Discs:
- A player shall provide at least one of his own discs as per
section 602.01. It is advised that an
additional disc be available in the event a disc is lost or becomes
unsuitable for use.
- C. Foul:
- No supporting point of the player shall rest on or beyond the foul
line at the instant of his release. A follow-through motion which
crosses the foul line after the release is permissable. Any foul shall
count as an unsuccessful throw and shall receive a score of zero (0).
- D. Measurement:
- A throw is measured from the point on the ground directly under
the disc when it is first touched by the player in his catching
attempt, to the closest point of the foul circle. Readings should be
made to the nearest cm. If the measurement point falls on or within
the throwing circle, the attempt shall be scored as a zero (0).
- E. Catches:
- The rules for catches set forth in section
603.03(E) of the MTA rules shall also apply to the rules governing
TRC.
- F. Time of Play:
- The rules regarding time of play set forth in section 603.03(D) of the MTA rules shall also
apply to the rules governing TRC.
- G. Score:
- A player's longest single throw resulting in a valid catch shall
be his score.
- H. Groupings:
- The rules regarding groupings set forth in section 603.03(G) of the MTA rules shall also
apply to the rules governing TRC.
- I. Starting Order:
- The rules regarding starting order set forth in section 603.03(H) of the MTA rules shall also apply
to the rules governing TRC.
- J. Interference:
- The rules regarding interference set forth in section 603.03(I) of the MTA rules shall also
apply to the rules governing TRC.
- 603.05. SCF:
- A. Play
- SCF combines the events of MTA and TRC by awarding a single sum of
points based on a player's MTA and TRC performances. All cuts in SCF
events shall include both MTA and TRC. The rules governing MTA and
TRC shall apply to SCF.
- B. Scoring:
- A single SCF score will be determined each round by multiplying
the player's MTA score by a factor of 5.5 (rounded to the nearest
hundredth) and adding it to the player's TRC score. For example, a
10.05-second MTA, worth 55.28 points, would be added to a 57.41-m TRC
performance worth 57.41 points, for an SCF score of 112.69 points.
604. Event Procedures
- 604.01. Judges:
- A. Accuracy:
- The head judge shall assign all players to their respective sites
and coordinate all other judges. The site judge shall be responsible
for timing the players, calling fouls and recording good throws. If
available, a second person may assist the site judge in calling hits
and misses so that the site judge may concentrate on foul calls.
- B. Distance:
- The head judge shall assign all players to their respective sites
and coordinate all other judges. The site judge shall be responsible
for timing the players and calling fouls. A measurement crew,
consisting of two persons, shall be assigned to each site, working in
concert to mark each throw at its point of impact and assist in
measuring the distance of the longest throw(s). A statistician shall
record all measured throws.
- C. MTA:
- The head judge shall assign all players to their respective sites
and coordinate all other judges. The site judge shall announce the
players, time their throwing periods, and determine and record the
official time for successful throws. The measurement crew, consisting
of four persons (three timers and one back-up), shall measure the
times of the throws with stopwatches.
- D. TRC:
- The head judge shall assign all players to their respective sites
and coordinate all other judges. The site judge shall announce the
players, time their throwing periods, and determine and record the
official distance for successful throws. The measurement crew,
consisting of five persons, shall mark each successful throw and
assist in measuring the distance of the longest throws.
- 604.02. Advancement:
- The number of players to advance after each round shall be
determined prior to the start of play by the number of entries in the
tournament. Top-seeded players shall be evenly spread throughout the
preliminary round. Order of play in later rounds is determined by
performance. See 603.03(H).
- A. Distance, SCF, MTA, TRC:
- (1) Competitions of 30 or fewer:
- Prelim--cut to 15 plus ties; Semi--cut to 5; Final.
- (2) Competitions of 31 to 80:
- Prelim--cut to 25 plus ties; Semi--cut to 5; Final.
- (3) Competitions of more than 80:
- Prelim--cut to 50 plus ties; 2nd Round--cut to 10 plus ties;
Semi--cut to 5; Final.
- B. Accuracy:
- (1) Competitions of 30 or fewer:
- Prelim--cut to 12 plus ties; Semi--cut to 2; Final--head-to-head.
- (2) Competitions of 31 to 80:
- Prelim--cut to 20 plus ties; Semi--cut to 2; Final--head-to-head.
- (3) Competitions of more than 80:
- Prelim--cut to 40 plus ties; 2nd Round--cut to 8 plus ties;
Semi--cut to 2; Final--head-to-head.
- 604.03. Ties:
- A. Accuracy:
- If ties must be broken, the tied players shall have a head-to-head
playoff with the first player to win a four-throw station advancing or
being declared the winner.
- B. Distance:
- If ties must be broken, the tied players shall have a series of
simultaneous throws in a head-to-head format with the first player to
win three of these one-throw matches advancing or being declared the
winner.
- C. SCF:
- If ties must be broken, the tied players shall have a head-to-head
playoff. The playoff shall consist of one MTA throw and one TRC throw
for each player. These results shall be combined in the normal fashion
to produce SCF scores. The player with the higher score advances or is
declared the winner.
- 604.04. Late Arrival:
- Players must be at the event site prepared to compete when called.
The competitive order of these calls is to be posted. In the event of
a player not responding to the official's call, the following
procedures come into effect:
- A. Accuracy:
- If a player fails to respond to the official's on deck call, the
next player in the order will be called. The absent player shall be
called again for the next throwing position. If he responds, he may
throw and a two-throw deduction is made from his score. If there is no
response to the second call, the player shall be listed as a scratch
(SCR).
- B. Distance and SCF:
- If a player fails to respond to the official's on-deck call, the
next player in the order will be called. The absent player is to be
called again for the next throwing position. If he responds, he may
throw but is only allowed three attempts. If there is no response to
the second call, the player shall be listed as a scratch (SCR).
605. Glossary
