First post here so forgive me for diving straight in. I've been riding a 20 mile round trip commute for the past year and love it. I live in London and have become very annoyed whenever I have to take public transport. It takes me half an hour to blaze through the traffic and saves me serious money.
The only issue is this; when I've not cycled for three days (if a take a holiday or whatever) I begin to get crippling cramps in my thighs (always the quads). Even the mildest activity brings them on, driving a car or walking 100 yards. The pain is enough to make me stop whatever I'm doing and lie down until they subside.
The really puzzling issue is that it only ever happens when I stop for 72 hours or more and they subside when I cycle though I get the odd small cramp for the first few miles. The doctor is stumped and is of the opinion that I should just keep cycling to ward it off.
Much as I like my bike I want to be able to take a few days off without being crippled.
Any ideas would be gratefully accepted,
