I hiked with a light pack with MapMyRide+! Distance: 12.31km, time: 02:04:53, pace: 10:09min/km, speed: 5.91km/h.
stopwatch says 3H 15m, the gps page over 3 hours. Maybe the terrain interfered with the signal because it said ‘paused’, ‘unpaused’ all the time
Anyway, it was hot, very hot: 35°C moderated by very strong wind.
