This series officially kicked off March 1st with Flat & Fast. In June and July for the Athlete’s choice and Countryside there is a new format as well where you have challenge monthly distances for swim, bike and run. By far the 336 miles bike is the most challenging to cover for the month. I have completed the 7.2 miles for the swim and 78.6 miles for the run. Each distance equals to (3 x the IRONMAN individual distance e.g 2.4 mile swim x 3 = 7.2 miles for the month).
