Just been reading and thinking about Timotea’s PB with the 5k. That’s the thing about running - the range of different achievements that each person can experience.
A quicker time, an enjoyable run, a longer distance, longer times, a quicker recovery, a hill tackled, a gremlin ignored, a playlist enjoyed, new learning from a podcast, a medal, a new route/road conquered, new people met (virtually or real-life), better health, better procrastination (!!)... the list goes on.
So, whilst I’m still a newbie, I reckon that’s what keeps folk at it, regardless of your ‘athleticism’, it’s all the very personal and individual achievements that come from running.
