I woke up with a sore foot this morning, which prevented me from going for a ride... As much as I hate it, I would rather rest and get better faster... I am walking with a limp atm, so riding is out... Not really the same thing, but my point is rest... Why give your body more stuff to repair? Just my two cents worth...
Probably depends how you feel. But take it easy! Very easy!
On the bush tours I go on for my annual holiday - often people with mild colds choose to keep riding - they just plod along, and take it easy. If they dont feel up to riding that day, or get tired - they take the sag wagon.
60-80 km a day at touring pace.
My experience - this is just me - if the cold isnt too bad - I can keep plodding slowly and I get there, and am OK the next day.
Other times I have really pushed myself hard to keep riding - and ended up very run down.
So depends how severe the cold is, and what I feel comfortable doing. I don't always get it right, though. Interesting to hear what others experience is.
I came down with a cold 2 and a half weeks ago - no riding for 6 days (my longest break all year). I rest first, then when no exercise gets too much after 3-4 days, mixture of local walking, stair climbing and gentle jogging (plus rowing machine). For me, the air needs to be warm to ride, otherwise the wind chill factor tends to freshen up the chest (even at my pace). Being warmer, went back into the Hills three days after nose had stopped. Missed out riding on previous Saturday with serious threat of continual rain - doesn't do me any favours when still affected. I did a longer Hills ride this week (warm) that did good (2 weeks after initial infection).
