Hi Sian
I am doing Carten too. I am also contemplating a Carten return on the sameday, depends on prevailing conditions on the day. If you have any muscle pain now, best advice is as already posted, rest ice compress and elevate.
I will be riding my commute tues and weds = 40 miles and nothing else strenuous this week. Definitely no plans for club 10.
