Despite reducing my interval time to 85 seconds on Monday, today was really my first session that I could do properly and it went ok. I completed all twenty 50m reps, though it was getting tough towards the end. I think that might actually be due to not getting enough calories on board at breakfast and then struggling to recover the situation in time after lunch. After a few minutes rest I attempted some 25m reps, but couldn’t manage as many below 19s as I did earlier in the week. That might be for the same reason. However, I did have three reps on 19.00, 19.01 and 19.06, so I wasn’t far out. I think 0.06 seconds is probably about the length of a finger.
Back tomorrow for another go.
