Training Run 66

Tonight's training session with the London Frontrunners involved sprint training with Chris McMahon.  We did 15 reps of 100m sprints, with short pauses between, followed by 10 reps of 150m sprints, also with short pauses between.  Although I can sprint quite quickly for very short periods, I can't maintain that level of speed for long and I felt as though I needed more time to recover between each rep as time went on and I became more breathless.  I know that I used muscles in this session that I don't usually use because I could really feel the aching sensation in both legs for the next couple of days afterwards.
