Yesterday in the afternoon, I was feeling perfect for a run session on the treadmill... 10.6km, inclination 1, speed 10-11km/hr! I then continued with a 50min rpm class, and 15min abs. I hopped on the bike to realize I was by then very tired! I could only cycle for 30min, resistance 7, and then I walked on the treadmill for 30min, inclination 5.5-6, speed 5.2-6km/hr. 15min of sauna were just not enough!
This morning I started my run feeling tired, but as I continued, I liked it and kept up the pace for 1hr:45min, about 16.5-17km.
