For a fit Olympic distance triathlete, this means 1 to 4 long bike rides around the 3-hour range. These rides fall within the last few weeks of training before volume tapers heading into race day. When I design a 70.3 training plan for athletes on a time budget, there are typically only two rides over three hours. In one of my ready-to-follow plans, the longest ride is at four hours. Many athletes have proven that it is possible to successfully complete a 70.3 race with a finish time between six and seven hours, having no more than one long training ride at the 4-hour mark.
