Today I went for a ride. From get go it felt as if I was riding with the brakes on. It was so bad I checked to see if there was a problem with my brakes. No, there were no problems with the brakes. It just felt so hard, even flat sections (no head wind) was difficult. I normally commute to work on my bike, but I have not been able to do that for about 2 weeks. But I did go on a quick pace ride the weenend before (35 miles) and it was OK. Today's ride was longer (60 miles) but from the start I was having a hard time. Do you ever get this feeling (riding with the brakes on)? Was it just an off day for me? Or did I do something wrong?
