Did I go for my run because a day without running is a day without meaning?
No.
Did I go for my run because I am a dedicated athlete and I know that every time I run, I am one step closer to achieving my ambition?
No.
Did I go for my run because the good runners of Twitter goaded me into it?
No.
Did I go for my run because I couldn’t face telling my coach that I hadn’t?
No.
In fact, I had just finished updating my plan with the note “Skipped. Simply couldn’t be bothered. Sorry.” when I saw that someone had given me Kudos on Strava for yesterday’s “Recovery run the first”. Which reminded me that today’s run was meant to be “Recovery run the second”.
I considered my options: I could change the title of yesterday’s run; I could accept that “Recovery run the first” would be stranded mournfully for all eternity waiting for its mate; or I could just get on out there and do my run.
I ran.

Oh the power of Strava!
I know! If I hadn’t chosen that title, I’d have been perfectly happy bunking off.
This is what makes you a Runner. Well done!
