I graduated from C25K in December but realised I’d only done 3.5km in the 30 mins, i.e an average 7km/hr. Basic maths shows you have to average 10km/hr to complete the 5km.
So I started it all again from W1 at 10-12 k/hr which is as fast as my heavy old bones can manage. Anyway, in the dreaded W5R3 I just covered 3.6km in the 20 minutes. I’m getting there and have eyes set on a 30m Parkrun 😁
