So I just did 5x800 with 400 jog rest in 2:15 2:14 2:13 2:10 and 2:01 which was definitely a tough effort but not 100% all out on the end. I've been doing about 70 mpw and have around 52 second quarter speed. I'll be racing a mile and 5k the next two weekends. Anyone have any predictions? I'll post an update with actual times after the races.
