I am running the Boston Marathon on April 17. Seven weeks later I will compete in my first long course triathlon [half ironman distance]. I have been competing in the Oly distance for the past two years.
Since I am prioritizing my running until Boston, I can only manage two [sometimes] three cycles per week. Further, since I live in a northern climate, most of my pre-Boston cycling will be on a trainer. Therefore, I will need to really put in some quality cycling following the marathon to be fit for the half ironman. Can anyone suggest a good short cycling training progression that fits my situation? Anyone had anything work particularly well?
