Hi, I started cycling 6 weeks ago. Initially it was on a 2nd hand Giant Rapid. I bought it to get myself fitter and drop a few stone in weight. Very quickly, I became obsessed. After a couple of weeks using the Rapid, I bought a Ridley Aedon 605A. I love it. I started just doing a few miles every other evening. 5 miles or so. I was so unfit. But I have built my fitness and lost over 20lbs. So I now do 15 or 16 miles every other evening. Avg speed is about 13 mph.

The issue I am now having is the last two times I have been out, I seem to have no power in my legs. I went out on Sunday past and did 17 miles.....great, I thought. Went out on Tuesday and had to go home after 5 miles. Just couldnt get my legs going. It was like cycling through water....very heavy legged. I put it down to fatigue. I went out tonight....and exactly the same.

I start off feeling good. But very quickly my BP shoots up and my legs ache and burn.

Any advice or help would be wonderful....

I have no idea whats going on. I am thinking of going back to the start again. Just going out for a few short easy miles and build up again.
