PICK A TRIATHLON

Super sprint
A bit longer than the novice triathlons but still nearly always involving a pool rather than open water. The bike and run elements are more likely to be on open roads.
Super sprint triathlons FAQs Sprint
The bike ride is usually 20km and the run 5km but the swim tends to vary from at least 400m if pool-based to around 750m if it's in open water. For ages 15+.
Sprint triathlons FAQs Standard (or Olympic)
This is the distance Alistair Brownlee won gold at London and Rio - a 1.5km swim (usually open water so wetsuits often required), a 40km ride and a 10km run.
Standard distance triathlons FAQs Middle distance
