Erm... failed. No hill sprints this week! Spent all day in bed trying to recover from dentistry, on the assumption that it were better to recover, and be 100% for DISC this week, than to do the hill sprints (or perhaps only part thereof) and miss out on DISC.
I, unfortunately, lack a control duplicate to tell me whether or not this was the best course of action. However I will be fine for DISC, so I can claim that as some level of success!
