I've gone snowshoeing every weekend of this month so far, which is great! But I've been having issues with my glucose when I go out to Kamview, which isn't great.
Jan 10th
On January 10th, my partner and I again went to Kamview. I used the same Snowshoe profile I made previously (70% basals), but this time did a 65% bolus with a known amount of carbs at 12:26pm. My glucose was 7.5 mmol/L at that time. We started snowshoeing at 2:59pm (a little later than I would have liked, but I was still doing okay); my glucose was 11.7 mmol/L at that time, and went up to over 12 as we started. My partner wanted to go further than last time, so after the initial 1 km (last time we turned back), we kept going, adding an extra roughly 1.5 km loop, then did the same 1 km return hike; our total was roughly 3.5 km.
Unfortunately at 3:39pm (after hiking somewhere in the neighbourhood of 1.2-1.3 km), we had to break because I was going low. We had to hang out on the path for around 20-30 minutes while I ate and drank some stuff and otherwise waited for my glucose to be high enough to continue on. Thankfully after the break, my glucose held for the rest of our hike. We finished at 5pm, with my glucose at 8.9 mmol/L.
So obviously I'll need to tweak things again before we attempt another hike at Kamview. I'm thinking I might need to try using my regular exercise profile (which is much more aggressive, running basals of 20%) the next time I'm out.
But then something interesting happened this weekend...
Jan 18
Yesterday, my partner, mom, and I went out to a friend's place to snowshoe. We were out for 1 hour, and I decided to use the unchanged Snowshoe pattern I had put together, along with the 65% bolus for a known amount of carbs a few hours before we went out (at 12:56pm). We started snowshoeing at 2:42pm, and finished at 3:43pm. My glucose was a little lower than I would have liked to start out (I believe it stayed under 8 mmol/L for the entire hour), but it held pretty steady. I did make a point of having some Gatorade in the first 20 minutes or so, too, to help keep everything stable.
I think this worked out for me because our friend's snowshoe trails are super flat. There was only one small, gradual hill, which was nothing at all like the terrain we were hiking at Kamview. So under these circumstances, the 70% basals and 65% bolus (with some Gatorade at the beginning of the hike) worked great. But if the terrain is more varied, I'll need to cut back all of my insulin a lot more than that.
I should also note that I've continued to do all of the boluses manually.
