I found ths run more challenging than W5R3. I managed to do it but didn't enjoy it in the most part. The first 5 minutes where a slog, I couldn't get comfortable. Half way through the 2nd run I finally relaxed and eased into it a little however it was over far to quickly then the walk pre last run again knocked me off my stride and I struggled through the last bit.
I went out tonight expecting it to be easier. I got there though and move onto W6 R2.
