Success! Yesterday I finished the Ironman 70.3 Calgary! It was grueling and boy am I sore today, but it was all well worth it.
For bloodsugar management I switched to lantus the night before at 75% of my normal basal and started the race around 200 mg/dL intentionally after eating a banana on the bus.
Although I wasn't wearing my pump (decided I didn't want to risk the PDM) I was wearing my CGM. So throughout the race I was able to monitor my bloodsugar.
At one point I was trending up above 250 mg/dL and so injected two units using a humalog pen which put me back in range.
During the bike and run I alternated between water and powerade as needed to balance out my bloodsugar. However, about five hours in, during the run, I was trending down while at ~80 mg/dL and switched to just drinking powerade in order to bring myself back up. I also had a Hammer Gel to sustain me through the rest of the run.
It was an incredible experience! There was a point on the bike when I was really hitting a wall but just then I passed another biker with "No Limits" on his jersey. That reminded me why I was here and kept me going!
A huge thank you to everyone who taught, guided and encouraged me throughout this journey. Without all of you this wouldn't have been possible.
