★★★Half Ironman TriStar Athletes - TSS projections based on intended bike split

This chart allows you to determine the total training stress and intensity needed for your upcoming half ironman race.  The higher your FTP, the faster you split and therefore higher your target intensity factor should be.  You should start with the estimated bike split first, then review your hardest rides to make sure you have done rides of this training stress (TSS) and then look to find the  corresponding intensity factor or (.IF).
