Well that wasn't bad at all. Hadn't looked forward to it as I found W1R1 hard and wondered if this would be a shock to the system too. It was definitely a bit more of a stretch than W1, but my body felt ready for it and I wasn't gasping at the end of any run. There are only 6 runs rather than 8 which was somehow a psychological advantage for me too. Bring on run 2!!
