20 minutes

Today was pacing my sister to run 20 minutes flat for 5km, it was much harder than it should've been to be honest and I don't know why I am struggling so much at the moment. Did another 5km after the race for 10km all up. Doing a long run tomorrow which I haven't done in a while so should be good. Wanting to be really fit again, I seem to lose it really fast.
