3 Miles was getting easier not so long ago but with the heat in Wandsworth I seem to struggle to make it even that far. I got to 3 miles today without too much fuss but I was feeling pretty lousy from the excessive heat. I walked for a bit and then ran for a further 6 minutes at nearly 1kph faster than my usual jog. My legs felt a lot looser once I started running but there was no way I could keep that pace up for long.

I should receive my heart rate monitor tomorrow so I'll be testing that out with a 4 mile run in the gym I think.
