6km of 8km Hard on Hills

Out late again....10:30 a.m. & already getting hot. Did 1km warm up, 3km of hills, turn around (hills still there!), 3km hills return, 1km cool down. I pushed the middle 6 km of hills hard, getting HR up to 90% (153) of max; 1km cool down, I practised the walking, bum-wriggle cha-cha; not easy & need lots more work! Singlet saturated with sweat by the time I got home, but felt it was a good session & that I was up to the challenge of pushing fairly hard on the hills. Actually, I think I'm feeling stronger each day now...hope it continues!
