Wetsuit outlook

Will you need a wetsuit at Triathlon y Bala — Legend?

Water temperature at inland lake in September has typically been 15°C, ranging from 13.8°C to 16°C in eight of every ten years. Against British Triathlon's thresholds for this race's 1900m swim, that means:

Wetsuit mandatory

Below 16°C a wetsuit is compulsory for a 1900m swim under rule 4.2(a).

What would have happened in each of the last 16 years

  • Wetsuit mandatory14 of 16
  • Optional (recommended)2 of 16

What the organiser says

Mandatory at or below 15.9°C; forbidden above 22°C (above 24.6°C for age 60+); sleeveless/shorty wetsuits permitted, socks allowed, gloves and boots not.

Estimated from air-temperature history — no direct measurement of this water exists, and small, shallow venues tend to run a degree or two warmer than shown. The official temperature is taken an hour before the start, and only that reading decides the rule on the day.

Transitions

There is no overnight bike racking — the transition area opens on race morning and closes around 30 minutes before the first wave, with no re-entry after that.
