Just above 20F. My coldest ride ever but wasn't too bad. Layered three tops and wore fleeced active pants and gloves. Body gets warm quickly but my fingers and toes are getting numb after half way (6-7 miles). But the bigger problem was somewhere else I never thought it would get cold. I would need better protections next time.
BTW, I feel much better after a fall last Monday at the intersection. Ride safe!
