I am fairly new to cycling and am training for a 2-day, 150 mile event. In the past few weeks I have been ramping up my distance training - 40, 60, 70 mile rides once a week on top of shorter hill training rides during the week. I have noticed that during the long rides, my pinkie and ring fingers start to go a little numb/tingly after 30 miles or so. I shake them out, adjust my position, etc., but the tingly feeling lasts a day or two after the ride. Does anyone know if this is typical due to my body getting used to longer rides, or am I doing something wrong and risking nerve damage? There is no pain, just this tingly feeling, kind of like when a part of you 'falls asleep' and then gets feeling back, but very mild.
