I wanted to go for a run the other day and it was pretty cold out. I’d spent all day sat cold in a draughty house and I also just wanted to have a hot shower and get under a blanket. So while I wanted to run, I wasn’t all that keen. Feeling determined, I put a lot of layers on and got a good 10km run in, nonetheless.

On the run itself I was too warm, after 10 minutes or so. Uncomfortably so!

The kit I ran in wasn’t optimal for the run. Without that kit on, I wouldn’t have gone for the run.

It’s important to know what we’re optimising for, to really be a good judge of what’s optimal.

I wanted to get out and chose optimally to do so.
