The idea is simple: run a 6,7 km lap every hour until there is only one participant left. (That 6,7 km/h pace is the pace needed to cover 100 miles in 24 hours.)⁣ ⁣ If you are up for a Backyard Ultra yourself, make sure to use SuuntoPlus Backyard Ultra sport app on your Suunto. It will give you key info, like the lap distance and remaining time until the start of the next lap.⁣ Our friends in Girona got together for Gina Backyard Ultra last weekend for some impressive runs and overall good times!⁣ ⁣ 📷 @rsalanova⁣ ⁣ #GinaBackyard @klassmark⁣ #BackyardUltra #Ultrarunning⁣ #SuuntoRace #SuuntoVertical⁣ #AdventureStartsHere」10月21日 16時00分
