So today I decided to run a new route, part in my local park and part out and down the main road.
2 laps of this makes up 5k of which aprox just under 2 k downhill and the rest up hill, ended up running 5.03 with an average pace 7.29
My fastest k at 6.27 with my slowest at 9.04 which was the last k and you've guest it uphill but this now has given me a new challenge and something to improve on
