SLSC Summer Aquathlon series 2026
The 2026 Summer Aquathlon series is on!
We have made some changes this year – partly in response to feedback partly due to the slightly later race schedule – reduced daylight. The planned races are:
- Wednesday 03 June – 1k swim + 5K run. CANCELLED
- Wednesday 17 June – 1 k swim + 7.5K run. RACE 2 RESULTS
- Wednesday 01 July – 1k swim +7.5K run. RACE 3 RESULTS
- Wednesday 15 July – 1k swim + 5K run. RACE 4 RESULTS
The 5k run will be 2 laps of the course, the 7.5K will be the usual 3 laps.
Registration (online only) will open on Monday 27 April 2026 and close for each race 48 hours before the race start to allow for pre-race admin.
Entry remains at £30 per race, SLSC members will get a £5 discount (please bring your SLSC membership card along when you race). This is not a BTF registered series but races will be run aligned to BTF rules.
On race day registration will open at 7.00pm and close promptly at 7.50pm to allow for the race briefing etc.
Maximum of 100 entrants in 2 waves of 50 people. The first wave will start at 8.00pm.
The race is a 1K swim (11 lengths of the pool) followed by a 5K (2 laps)or a 7.5K (3 laps) run around Tooting Bec Common (sign-posted circuit). A maximum of 100 people can take part – we typically have 2 waves.
The course record currently stands at 39.17mins for the 1K swim + 7.5K event.
Series Winner(s)
The Race Directors will decide overall series winners at the end of the 4th race. To be considered you must have participated in at least 3 out of the 4 events in your age category. The best part is the winner will get a mug!!!!! Age categories are:
- 17-39
- 40-49 (veteran)
- 50+ (super-veteran)
This event is run entirely by volunteers and as with all SLSC events we are always in need of volunteers to help us make our events safe and fun. Being an SLSC volunteer is a great way to meet new people, put names to faces at the Lido and generally have a good time. If you can spare an hour or two on race days please do come and help our Aquathlon Team with time-keeping and marshalling the run route.
