It was an early start for me as the bookings for residential school opened at 09:00 and are allocated first-come, first-served. I didn’t want to end up having to go to Nottingham instead of Bath so I made sure I got my 5km out of the way so that I could be showered and at my computer when the bookings opened.
You get different people out on the river path earlier in the morning, but I was taking it slow and steady (and walked back for the remainder of the Zombies, Run! mission once I hit 5km).
