Its not just the duration of the race. There's so much thinking hours before and hours after.
Last night I ran a 10km race with a friend of mine. ALL went surprisingly well. Isn't is always a surprise when things go well? It is for me, I always expect something to screw up my plans. I finished in 1:05, certainly not my personal best. I've never been a fast runner though, my strength is long lasting endurance. 1.5 hours before the race I set my temp basal for 25% at which point my BG was sitting around the normal mark and I didn't eat anything. At the start of the race my BG was at 10.8 (195) at the 5km mark I was at 10.4 (187). By 7km I hit my runners high and kept up a faster than usual pace for the remaining 3km. Upon finishing my BG was sitting at a super lovely 7.3 (131). I couldn't ask for anything better at which time I ended my temp basal and bolused for a banana.
I never stop learning when it comes to exercise. EVERYTHING leads to a new lesson learned. Moral of the story? After an evening race (or long run), set temp basal for something like 85% for a few hours and maybe half breakfast bolus the next morning. At least that's what I'm going to try anyway because a race for a PWD isn't just a race. It comes in three parts. The before, during and after. Our brains never stop computing. Next stop, half-marathon in October.
