Is this possible? Not trying to do it fast, just do it. My schedule calls for three rides per week with one long ride on the weekend and two other rides during the week. The total weekly mileage builds up to 122 miles with the longest ride before the event being 65 miles. I may try to get to 75 or 80 though. I am running 3 to 4 days a week also. Will the running help my endurance enough to make up for only riding three days?
I'm trying to balance running and cycling and having a bit of a hard time. But triathletes do it all the time (plus swimming!) so I know it can be done.
