I'll be honest: W6R3 was the first run I failed.
Five minutes in something just wasn't right. My legs seemed anchored to the ground by lead weights, each step becoming increasingly more painful than the last. At 15 minutes I had to stop and walk for a bit and, although I did barely manage 25 minutes of running total, it wasn't continuous.
I was so bummed.
I almost didn't run today. Why bother? I knew that I just wasn't built for physical fitness - 15 minutes is all I'll ever be able to run before collapsing into a hot, sweaty mess. I can't do it. No. Stay on your sofa. Order a takeaway. Relax, after all, you deserve it.
However, I did make myself a promise: Go for a run and just go for as long as you can. If you really hit a physical wall, stop - after all, a short run is still better than no run.
I kept that promise. I ran until I could run no more. And I didn't run for 25 minutes.
I didn't run for 28 minutes.
I ran for 30 minutes. Nonstop.
Admittedly, it was more of an enthused jog than a run (I was pacing myself), and yes, by the end one of my feet had gone completely numb, but I still manged it. A few months ago, never in my wildest imagination could I see myself running for 3 minutes, let alone 30.
I'm posting here as a cautionary tale. I had such a negative mindset. I was thinking "I'm going to run for 15 minutes, have to stop, and this run will be yet another failure" when I should have been thinking "even if I only manage 15 minutes, this run will be a great success because that's still 15 minutes more than I was doing 2 months ago". So if you fail a run, don't feel discouraged; instead of thinking 'never' think 'next time', even if 'next time' actually winds up being 3, 5 or even 10 runs later. Because you will only ever get there by not giving up.
Bad runs happen, true, but the best part about them is how they make the good runs all the sweeter.
