1. Age 68
2. Average 300-400 miles per month, sometimes more.
3. Ride is a Specialized Explorer "comfort" bike.
4. Speed is not really an issue but mileage is and I usually ride 5-6 days/week.
I found that I was getting slower and slower while doing the same mileage every day/week.
I also found that while I didn't feel "bad", I was feeling tired a lot.
I tried laying off for a couple of days a few times and that didn't do any good so.........
I went to see my Doctor. Got checked out and found nothing abnormal. The Dr. set me up for bloodwork and low and behold...........everything was fine except I was low in IRON which would cause the symptoms described. Started taking an iron tab every day and everything is back to normal. Not tired, speed is really better than ever before and the legs are strong.
The lesson learned:
Don't try to tough things out. Find out what the problem is and fix it before it becomes a really big problem.
BTW: Am considering getting a lighter bike. Any suggestions considering the type of riding I do?
