Triathlon speed calculator – how it works
1. First, select your distance or specify the routes for which you want your times to be calculated:
- Long distance (3.8km swimming, 180km cycling and 42.195km running)
- Middle distance (1.9 km swimming, 90 km cycling and 21 km running)
- Olympic distance (1.5 km swimming, 40 km cycling and 10 km running)
- Individually
2. Enter your planned times for each discipline – including the transition times between swimming, cycling and running.
3. You will then automatically receive your times for swimming - cycling - running without transition as well as your total time.
