Ok, so I've just come back from w5r2. It wasn't easy, but I did it (I guess there'd be a problem if I found it easy!! ) But the whole way round, the little voice in my head kept saying 'thank god it's only 8minutes, thank god it's only 8minutes, oh my god on Thursday I have to do 20 minutes, I'll never manage 20minutes!!!'
I just can't imagine being able to run for more than double what I did today with no break! Argh! Up until now, the slots have seemed sufficiently small to feel manageable. But 20minutes just seems like FOREVER! any tips from those of you who have done it?
