Long distance riding while carrying a lot of gear .....? |
On long ride my heart rate monitor show usualy 150 to 170 beats per minute (depend on hills) , my cadence is about 95 and I noticed that I did feel one moment little short of breath ,( no head wind and no hill , gear 52 - 11 , temperature 22C , behind me 25 km ) one moment also I start sweating so badly , had blure vision and finaly I had to stop and take the rest . It happened to me for first time . I did continue riding after about 1/2 hour of rest and symptoms disapear . From that moment I feel just fine . What went wrong ? Has anybody this experience ? One moment in the saddle I did feel that I will have blackout . It sounds like dehydration. The temperature was not too hot and you had not riden too far, so it seems a bit strange. In your discussion you do not mention drinking any liquids. How much had you had to drink up until then? As far as being out of breath, I do not know how old you are or what your maximum HR is, but for me 160 is about my anaerobic threshold, so as I start going above that I start getting winded. I have also had similar symptoms (light headedness) in the Spring on the first warm (22C) day. I attribute that to acclimation to the weather after riding in cold temperatures. Another thing that comes to mind is hypoglycemia (low blood sugar). When had you last eaten and what did you have to eat? That can make you light-headed. It is very hard to diagnose without more information, but any or all of those things could have contributed. I suggest that you make sure you drink plenty of fluids and if you are doing a long ride, take something for energy; energy drinks and/or energy bars of gels. On an average temperature day I finish off a normal sized water bottle in 20 miles and as it gets warmer I will come closer to two bottles (I suspect you are from Europe, so I am hoping that the water bottles are similar is capacity). I hope that helps some. Safe cycling. Not to scare you but... I was racing about ten years ago and similar thing happened to me, I ended up having heart surgery - bad heart valve. See a doctor tell them what you experienced to help them look for something that might do this. While my case is extreme - better safe than sorry. Yep, I agree with cyclist (above). You should be fully hydrated before riding. The best signal of this is to drink until your pee is clear... this is an old racers trick. You should be drinking about 1 bottle of water every 10 miles- more if it is hot or if you are exerting yourself. You should also not exceed 80% of your maximum heart rate which is figured by subtracting your age from 220 then multiplying by .8 I am 45 so my max rate is 175, and 80% of that is 140. This can vary of course, but it is a quick rule. Just BE CAREFUL! 27 years in the industry |
