Orienteering race (forest/urban) 36:22 [4] 5.4 km (6:44 / km)
ahr:167 max:174
LL event, the rest.
Annoying that I didn't get the whole picture but 35mins is a good enough full effort test. Avg. HR of 167, max 174. So all I need to do now is see how high I can get the HR fast walking and that is the start of zone 1 and 167 is the end of zone 4, or something like that.
