4.5 miles of hill workout on treadmill at 7:00 pace, level 9. 1 mile warmup. 1.5 mile cooldown. This didn't go too well. I made it through 2 miles, rested for 2:45, 1 mile, rested for 2:45, 0.6 miles, rested, 0.5 miles, rested, 0.3 miles, rested, 0.3 miles, cooled down. So in total, I had to stop and rest five times. It's getting harder for me. My heart rate just gets so high that I'm afraid I'll pass out. I will keep working these hills and see if I can improve. The heart needs to get stronger. Plus I think I could have done better if I had taken it easier on my Tuesday run. It was just hard to hold back. Anyway, I'm pleased with having pushed myself and will keep at it. I hope everyone is having a great Christmas and that you're not reading this on Christmas! |
