I run 3 times a week, 2 X 5k and a longer run. I have entered a half marathon in September so feel I have been reasonably sensible but running 20k seems a huge goal for someone who graduated from C25K 32 weeks ago now and as a 52 year old former non runner, pretty surprised I run at all.
I have done 10k quite a few times now which is good but once did a 13k, so today with a 10k in mind, I felt OK and kept going to 11, again at 12 and so thought I might stumble a little longer and managed 15k! A record for me and makes a half marathon in September seem possible. Lovely grass and tracks in the woods too, so great for my chunky legs!
