I've just got in from this morning's tandem commute, walked around a bit, and noticed a pain in the top front of my right foot. I actually noticed then, it REALLY hurts to bend my foot upwards.
I think this has happened, because my feet are used to letting the hard soles of my cycling shoes transmit the power to the pedals, not doing it themselves as they have to on the tandem as I've been riding it in trainers.
I'm guessing this maybe tendonitus?
This is a really bad time to be laid up. Am as stupid getting back on the bike today? I've several errands I need to run!
