Achilles tendon

Just rode from Brighton to Eastbourne down the coast road/A259 which is only just over 20 miles.

Quite a bit of climbing and descending however.

Did it on 50/18 and my right tendon is creaking again- and is about twice the width of my left tendon.

I'd like to ride back tomorrow- is this stupid?
yes, yes it is, sounds like classic tendinitis, ive had it in my wrist before from rowing, the more you aggravate it the worse it will be/the longer it will take to heal, trust me on this, if you aggravate it, it will take months to get better. . . i had it really bad i only recovered so as to be able to row again last month when i had damaged it in april! though you have to take into account that i was rowing 6-7 hours a day for a whole week. . .
