TrainerRoad has sprint plans. Most of their plans also include run and swim workouts alongside the bike workouts. I have not looked in the Sprint plans, though.

What is your goal (finish & feel good, podium or win AG, finish top xx overall)? What is your current ability? I routinely podium sprints in the same AG as you, but I train about 10-12 hours/week for HIM. I am not sure I could win AG if I trained any less.

I have only done four sprints so far, and in my humble opinion, it is all about the bike technology, transitions, and the run.

• Swimming speed, regardless of distance, is pretty much determined by volume of swimming. And, the top swimmers rarely win sprints on their swims alone. So, you really only need to be in the upper end of the next tier of swimmers (the faster regular people).
• The bike is largely determined by absolute power and the technology you bought. So, just put in the time to increase power.
• Bike technology is a huge factor too. Buy tech (good TT bike with fit, aero helmet, aero tri suit, wheels) to increase speed which will cut your time by 2 - 4 minutes. Top AG finishers have all the bike tech.
• T1 can give you 15 to 30 seconds if you merely hustle, ride sockless, and rubber band your shoes on your bike.
• T2 can give you 30 to 45 seconds if you get quick lace shoes and run sockless.
• Run: This is the money. Top >50 AG finishers are rarely running slower than an 8:00/mile pace. You need to be sub 7:30 to play. Put in the time with speed work, coupled with bike endurance, and you will earn time in the run that will protect a weaker bike or swim.
