I have a question regarding century training:
My son lives in Tucson and we are going to do El Tour in November. I am mostly a mountain biker. Don't ride on the road much except when the trails are too muddy to ride. I spend between 50-60 miles a week on my mountain bike, uaually at 8-10 mile mph. Lots of up and down, mostly single track. I feel like a need to add a long road ride once a week to get ready to ride the century but not sure of the progression. Seems like I should start in August to get ready. Can't cut out the mountain biking as it is connected to my job and the distance is pretty consistent week to week. Fairly unique situation, I know so looking for any thoughts. I have done some endurance mountain bike races but never a road century. Thanks in advance for any help.
