So, I just did my first Short-track MTB race this past Saturday, and ran into a little snag with my BG due to the adrenaline rush. I dropped down to about 75 an hour before the race, and had a packet of Gu to bring me up a bit before I went out to practice. My BG was about 235 15 min. before, so I gave myself a small bolus (0.3 U) to help bring me down. I was wearing a CGM, and my glucose was holding steady in the low 200s at the start of the race.
The track was pretty difficult, and on top of this it was my first race EVER and I was borrowing a teammate’s bike. For the first few laps I felt really jittery and also very parched, but about 3/4 of the way through I started to feel kind of weak and shaky, like I might be low. My CGMS also started alarming at this point, but I wasn’t in a place where I could look at the screen to see if it was a high or low alarm, so I just ignored it and figured I’d keep riding until I had a problem. Then, I wiped out on 2 steep uphills in a row, and after I clawed my way up to the top of the 2nd one I stopped to look at my pump - BG was up to 275. So, I kept riding and finished (I got 3rd place, and some SWEET bruises!).
Obviously, I should have taken a larger bolus, but I’m not sure at this point how to plan and bolus for an adrenaline rush, or i I’ll have the same problem next time I race… Anyone have any experience with this?
