Have noticed that before parkrun, my BG goes up more than usual prior to running, then really drops. Wonder if anyone has seen similar effects on race days and what their strategy is for managing this?
Take this morning for example:
Before breakfast - 10.3, took normal insulin dose which usually would hold this BG
Pre exercise - 18.8, no ketones, did not take insulin
Post exercise - 6.2
It's normal in my case to see a drop of about 10 in my BG when doing 5k distance generally.
BG doesn't drop as much when I go slower e.g. at 10k pace. Have also noticed a flat out 5k really seems to get my heart rate up: have recently got a monitor and seen max HR go 9bpm higher during parkrun than I managed in a max HR test!
Can imagine the best way to control BG in this scenario might just be to take on more insulin before breakfast, then take on a snack just before the 5k so carb takes effect while I'm running? Alternatively, I wonder if increasing novorapid but cutting levemir in the morning could work?
