I've not done the Runner's circuit at Fairplay Sport since the beginning of January due to the combination of the leader being in Australia, the swimming class and Christmas break. I didn't push too hard as it felt hard and rather unfamiliar; sentiments I believe echoed by the other participants. Even though I'd done a few blocks of exercises at home over the holiday I don't think I'd done an intense 30 minute session. Of course, that's the key benefit of an organised programme, you tend to go along with it rather than think 'that'll do'.
Of course, being a Wednesday, it was raining.
