Can somebody explain this heart rate anomaly to me?Fez

Today was the first day I rode with long tights, long sleeve jersey, full fingered gloves (still thin), shoe covers, etc. Temp was high 50s. Speed, cadence, overall physical feeling was OK. Didn't feel overly strong, but didn't feel weak either. But I noticed my heart rate averaged 15-20 beats higher than normal throughout the ride. I have never seen this happen before.

1. I am not overtrained or fatigued. In fact, I have taken it easy for the last 2 weeks due to wet weather and the DC area sniper scare. Could the sniper have caused so much anxiety that my HR was elevated?

2. I think I dressed just right for the ride. But does cold temps make the heart beat faster until you get used to it? I've only been using the heart monitor for a few months so I haven't used it in the cold months yet.

It was the wierdest thing. If I didn't use the HRM, I wouldn't have noticed anything different. Everything felt normal, except the HR reading was 15-20 beats higher.

This is a longshot, but maybe your heart has to work a little harder in cool weather since your body has to expend more energy to keep warm.

All I know is that I commute year-round and always feel more sluggish in the colder months. My average speeds reflect this too...

From what you explained, nothing was abnormal except your reading on your HRM. Is everything in good working order with your HRM? Did you take your pulse by hand to see if the rythyms matched your read-out? I would also say that if you are riding, looking over your shoulder for a bullet to come whizzing in your direction, and it weighs heavily on your mind, I would say that's good for at least several BPM. Scary stuff man.

You were slightly dehydrated. Did you have a couple of beers the night before the ride?? Alcohol dehydrates. Personally, I have noticed the same thing with my rides. It almost always comes after a night 'out' or when I knew that I didn't drink enough water the day before the ride. Notice I said the day 'before' the ride - much more important regarding hydration than the morning of the ride. It's not gonna kill you, just decrease your performance.
