What the averages leave out
The wetsuit decision rests on the temperature measured on race morning. Under the 2026 IRONMAN Competition Rules, age-group athletes may wear a wetsuit up to 24.5 °C and must wear one below 16 °C. The averages of the Canadian half distances, from 17 to 23 °C, all sit in the range where a wetsuit is allowed. Victoria's 2024 reading, 16 °C, was at the compulsory threshold. The wetsuit rules guide sets out every threshold.
On 26 October 2026, ironman.com showed IRONMAN 70.3 Muskoka, IRONMAN 70.3 Mont-Tremblant and 5150 Mont-Tremblant sold out for 2027. Prices on the race pages are in Canadian dollars. At Barrelman, athletes without a Triathlon Ontario membership pay a one-day fee of C$12 on top. Registration is always done on the organiser's site.
