Heat exhaustion mystery solved

Sunday, August 31st, 2008

Starting sometime last year, I started having problems with heat exhaustion on longer, more challenging rides. The funny thing is that no matter how hot it is, it’s not an issue on shorter rides (less than 100 miles). Last week, I found out why.

In preparation for the Everest Challenge, I climb Mary’s Peak 3 times every Saturday or Sunday. Last week, I strapped on a heart rate monitor and rode the same as I normally do just to see how hard I was working. I discovered that even on extended rides, my HR is over 160 a lot of the time and practically never drops below 155 except when I’m going down a hill. That’s fine if I’m on my trainer in the garage for an hour (in fact, I’ll take my HR higher than that). But putting those kind of numbers up hour after hour? I had no idea I was doing that — no wonder I felt so bad.

Today I did Mary’s Peak again with the HRM strapped on and took it easy. I tried to keep my HR around 145 most of the time and didn’t spend much time over 150. It was a totally different type of ride. My second climb was faster than the first, and my third was faster than the second. Plus, I was able to enjoy the scenery.

The bad news is that my average speed that was 0.7mph slower than last week — that’s huge in cycling terms. Nonetheless, I was happy with the results. I could have easily done another lap. Just for the heck of it, I cranked up the effort near the end to see how much strength was left, and there was plenty of gas left in the tank. Even though I lost almost 18 minutes during the ride, I was in MUCH better shape afterwards, so I think I’d recover the lost time if I had to stay out much longer. Things are looking good for the Everest.

Bryan wants to go riding tomorrow and put the hurt on me since he figures I will have ridden too hard today. I’m looking forward to it….

Not as bad as I thought at first glance

This past weekend, I took part in the Shasta Super Century. It’s challenging, the scenery is fantastic, and its my favorite ride of the year. For the past two years, I’ve been using it as a training ride for the Everest Challenge.

A few minor snafus aside, most of the ride went well. I forgot to fill my water bottles on the day of the ride and dropped my arm warmers into the porta potty (ugh) at the top of the first mountain. Starting around mile 80, my left knee started acting up, but I cut through the first 100 miles in my fastest time yet by a significant margin.

As I started the final climb, things rapidly fell apart. Heat exhaustion symptoms set in and my legs started cramping. I didn’t take breaks on any of the other climbs, but I wound up stopping numerous times on the last one — including taking a half hour nap on the side of the road only 1.5 miles from the finish. I decided to scrub my plans for the Everest.

I often forget how tough the Shasta is — the whole point of rides like these is to challenge strong riders. The first year, I did the entire final climb in a stupor, my legs were screaming in pain when I reached the top, and I almost didn’t make it. Looking at my blog posting for the Shasta last year, I see I did better then I did the first year, but that pain and heat exhaustion were major issues.  I also see that despite all the problems I had yesterday, I did much better this year.

In short, the Everest is still on. There are 5 weeks to train, and too many things could happen before or during the ride for me to predict an outcome, but my chances at this point in time look decent.
