Since the recent spell of hot weather I have been increasing my daily distance. I am going for a ride during my break, taking longer routes home, and also going out for an evening ride or going to the gym and/or using the Wii Fit. Not surprisingly I am getting muscle cramps in my legs (and sunburn). Should I take it easy for a few days or grin & bear it and hope my body gets used to the new (temporary) regime??
