Was up and out by 6.45am this morning. The only problem was I hadn't anticipated quite how dark it would be. I skirted around Morden Park looking for some dog walkers but all was pitch black so I reluctantly stuck to the road.
i managed to get past the 5 min barrier - probably as I was preoccupied with the route. Am now running for 16 minutes but still getting overtaken by fast walkers :-)
