I left yesterday’s marathon training update on a gloomy note. I was still disappointed in myself for not being able to complete the planned 17 miles. But I’ve been doing a lot of thinking, and reading. I get these articles aimed at the MS community, and two came in the last few days talking about heat intolerance and multiple sclerosis. This is not a new concept to me, I’ve known all along that as someone with MS, I need to be careful about the heat. I guess I just sort of forgot, you know? Because of the damage MS has done to my central nervous system, my body is more sensitive to heat. Even a slight increase in core body temperature can cause my nerves to misfire, leaving me with pseudo flare-ups, fatigue and muscle weakness. So. The fact that I am attempting to run all these crazy long miles in 70-80 degree heat is a little bit foolish. No, it’s more than that. It’s pretty damn stupid. Probably dangerous. Definitely a bad idea. So I’m giving my overachiever self a little slap on the wrist, and telling her to find a different way to accomplish her training. It can still be done. We have access to treadmills and fans and air conditioning. Sure, it’s not as scenic or entertaining, but it’s also only temporary. Summer is quickly coming to a close, and then we can get back out and run on those lovely trails. Okay, Mel? Work smarter, not harder. Now carry on. Lecture over.
