Running along

After thinking about it for a long time, last week I finally got round to replacing my old running shoes (I had been waiting for shops to reopen, but I went online in the end).

In the fifteen months I had these shoes I ran just under 1200km*. That’s way, way over the recommendation of replacing running shoes after 500-800km. My usage averages out to about 2.3km per day. Obviously I didn’t run every day – some days I ran more and some days I didn’t run at all.

*I’m not sure this is quite right as there’s some activities which I wouldn’t have used these shoes for but are recorded with them. Conversely, not all my runs get recorded so it may balance out. Anyway, it still shows I went way over the recommended usage limits.

Distance (in km) against time

There’s a few interesting trends to pick out from this data:

  1. It’s possible to see where I had big races in my schedule. I ran half marathons (21km) in March 2019 (the Big Half), September 2019 (the Great North Run) and early March 2020 (the Big Half again). These all show as an increase in training over the proceeding weeks (more distance covered), a small step increase for the race and then a reduced mileage afterwards.
  2. I also ran a half marathon in August 2019 (the Thames Meander Half Marathon) which again shows as a small step increase, but this was part of my training for the Great North Run so doesn’t have it’s own associated training increase/decrease either side.
  3. I appear to have taken a fairly long break from running in March-April 2019. This was partly from resting after the previous race, but also mainly because I was out of the country. I had taken an older pair of shoes to save on weight (not because my older shoes were lighter, but because I could use them for non-running purposes too – something I wouldn’t do in my almost new shoes).
  4. I also ran less in December 2019-early January 2020. I had a cold/illness at this point (even if my family didn’t believe me) and I didn’t feel like running for most of the Christmas period.
  5. Since the most recent race at the beginning of March, and during the lockdown, there’s been a steady stream of runs, some slightly longer ones but balanced out by some extra rest days. Without any races planned, I guess that’s what my regular running pattern looks like (i.e. when not training for a race and not resting after one).

Anyway, after almost 1200km and four half marathons, it was definitely time for them to be replaced. Time to see how their replacements hold up…
