Para Swimming

The sport

Para swimming is swimming — the same four strokes, the same pool, the same distances scaled to class — for athletes with physical, vision and intellectual impairments. It has been on the programme since Rome 1960, where 77 swimmers from 15 countries contested 62 medal events, all of them athletes with spinal cord injuries.^[1]

It is the second-largest sport at the Games and is practised, on the federation's own figure, in nearly 100 countries.^[1]

Governance

Governed by the International Paralympic Committee as World Para Swimming, administered from Bonn. Like Para athletics, its transfer to an independent federation went to exclusive negotiations with UK Sport and Manchester in 2023 and was reopened on 6 June 2025 with no successor since. The chronology.^[2]

Technical rules otherwise track those of World Aquatics, and the current edition took effect on 1 February 2026.^[3]

Classes, and the prefix that is not a class

Three prefixes, and only two of them are classes.^[4]

• S — freestyle, butterfly and backstroke.
• SB — breaststroke.
• SM — the individual medley, and expressly not a sport class but an entry index.

The ranges are S1–S10, SB1–SB9 and SM1–SM10 for physical impairment — note that SB stops at 9 — plus 11–13 for vision impairment and 14 for intellectual impairment. Lower numbers indicate greater activity limitation. A swimmer very commonly holds different numbers for S and SB, because breaststroke loads the body differently from the other three strokes: physical classification is a points assessment across arms, legs, trunk, the start dive and the turn push-off, scored separately for the two stroke groups.^[4] [5]

The medley index is then derived from those two numbers and rounded to a whole number, rounding up at .5:

• S5 and above, swimming a four-stroke medley: (3 × S + SB) ÷ 4
• S1 to S4, swimming a three-discipline medley: (2 × S + SB) ÷ 3

Athletes in class 14 must first satisfy Virtus eligibility, then a sport-specific cognition test battery, and — where they fall in a defined middle band — an observation in competition that is conducted stroke by stroke.^[5]

Tappers, goggles and six ways to start

The tapper. A swimmer who cannot see the wall is signalled by a person on the deck with a pole. For classes S11, SB11 and SM11 tapping is mandatory at every turn and every finish; two separate tappers are used where both ends of the pool need one; and the device must be approved as safe in construction and length. The tapper is Support Staff designated by the National Paralympic Committee, not supplied by the organiser — which is why the penalty structure matters: swimming without a tapper is not itself an offence, but surfacing in another swimmer's lane without one is a disqualification, whereas the same thing with a tapper is not. In distance events the inspectors of turns notify the tapper, not the swimmer, at 15 metres and two lengths to go.^[3]

Blackened goggles. All S11 swimmers, other than those with prostheses in both eyes, must wear opaque goggles, checked at the finish of the race. If they fall off on the dive or break mid-race, there is no disqualification.^[3]

Starts. The rules provide six lawful variants beyond the standard dive: orientation on the long whistle before "take your marks"; a balance hold at the hips, hand or arm by one member of support staff, who may not impart momentum; a dive without a foot at the front of the platform; a start beside the platform; a seated start on the platform; and a start in the water with one hand in contact — standing in the gutter or on the bottom is prohibited. Athletes in classes 1 to 3 may have their feet held to the wall until the signal. Where a swimmer cannot grip, an approved starting device may be used.^[3]

Prosthetics are banned in the water. Rule 11.8.9: "No Athlete shall be permitted to use a prosthesis (except ocular), or orthoses during the race." Cochlear implants and insulin pumps are expressly permitted.^[3]

Relays run on points. Each swimmer's class number is its point value, and a team must not exceed the cap for the event — 20 points for the 4×50 m, 34 for the 4×100 m, 49 for the vision-impaired relay, which must include at least one S11 swimmer. Mixed relays carry the same caps and must be two men and two women. Declaration forms exceeding the cap are simply not accepted.^[3]

Competitions and records

Below the Paralympic Games sit the World Para Swimming Championships, biennial, then a sanctioned tier including the World Series and regional championships, then two approved tiers. Records may be set at the top four tiers only.^[3]

The most recent World Championships were Singapore 2025, 21–27 September at the OCBC Aquatic Centre — over 580 athletes from 75 nations, the first edition held in Asia. A 2027 edition is built into the LA28 qualification pathway but no host had been announced as at 29 August 2026.^[6] [7]

The World Series, launched in 2017, ran nine meets in 2026 from Gold Coast in February to Abu Dhabi in November. It is scored as a season-long virtual competition: every result is converted through a standardised points system, so the series winner is the best performer across the season rather than at any one meet.^[8]

LA28: 142 medal events, quota 605, 17–26 August 2028 — one event more than Paris 2024.^[9]

Records require a surveyor-certified lane length, a licence held before the competition began, and a sport class status of Confirmed or a fixed review date after the record year. Where the swimmer's status was under review, the national committee has six weeks to present them for classification, and the record is ratified only if the class is validated. Doping control must have been conducted at that competition. Relay split times can never be used for records, and an athlete may only set records in their own class.^[3]

Who has won the most in para swimming?

Para swimming has been contested at every Paralympic Games since 1960 and is the second-largest sport at them — 141 medal events at Paris 2024 against 35 in Olympic swimming — so the longest careers here run to more medals than the Olympic sport has room for. The tables cover all seventeen Summer Games. Class codes have changed under the athletes: Trischa Zorn's medals are recorded as letter class B, then B2, then S12, SM12 and SB12 — six labels for one impairment. Her total is also the one figure here that departs from what almost every source prints. Zorn is universally described as the most decorated Paralympian of all time with 55 medals, 41 of them gold; the IPC's own database records 32 golds, 9 silvers and 5 bronzes — 46 — and that is the figure used here. Either the IPC's archive is missing events from the 1980s Games or the popular figure is inflated; she leads on either count. Counted from the IPC database, which reconciles to its own total of 7,494 medals, with every athlete row re-counted from their results tables rather than the IPC athlete-page counter, which also includes World Championship medals. Olympedia does not cover the Paralympic Games.

Medal lists rank on total medals, then gold, then silver. Equal totals are separated by golds, then silvers, and every table states the period and the Games it includes. National Paralympic Committees are listed exactly as the IPC counts them, including historic and neutral entities. Verified September 2026.^{[10] [11] [12] [13] [14]}
