Pedaling like a madman downhill is also fun, on loose crushed stone stopping is sometimes bit interesting tooAbsolutely fun to blast up hills and free fall down the other side.
I have noticed GPS is bit poor with elevation, for example from last graph, where there is highest heart rate, climb is over 7%, 17 meters in 238 meters distance, but GPS claims it to be only 5 meters and 330 meters distance which would be only 2% climb.
Also that steepest downhill is really 20m drop in 130 meters, that is around 15% (fun to go uphill, leg burn hill!), but GPS is missing almost all of it as it lags quite bit behind, especially with elevation.
Luckily we don't have those long steep climbs like on mountains, I would be stuck in a valley then.
