Just back from W5R1. This was the first run I've done taking the dog as well. He seemed confused as to why his 'walk' was running to and fro along the same stretch of bridlepath but didn't complain!! I found the first 5min run hard, the second ok and the last one was best of all - seemed to get my breathing better. Will do W5R2 hopefully on Wednesday but might repeat W5 as I've got a 10k charity walk for the local hospice on Friday night so definitely won't being doing the third run on Saturday!
