I began to get back on the saddle last month. Started off with an hour of spinning on the trainer to get the feel of it before doing my road rides. Then I gradually started to build mileage on the road and had a two 80km ride during the Holy Week. I have now included cycling in my training regimen, 2 weekday rides, and 1 weekend long ride. Probably I would insert a brick session (bike-run) in one of my weekday rides.
