Time measurement is done exclusively with the ChampionChip!
The ChampionChip is a small plastic transponder that has to be fastened on your running shoe (no metal contact!) and will measure your personal race time.
Your net running time can only be measured if you step on the contact mats laid out on the starting and finishing lines. Likewise, you must step on all mats laid out on the route.
Intermediate time check - you will be disqualified if your intermediate times are not recorded.
