Length: This 16 week program is an Intermediate Plan for the time-constrained 70.3 athlete (an athlete who has successfully completed a 70.3 in sub-6:00 and is looking to complete another with a more efficient training schedule). The plan averages 8 hours 20 minutes per week and has a max week of 12.5 hours; all but three weeks are 10 hours or less. A typical week has 1-2 mid-week swim/strength and 2 mid-week bike/run days each totaling no more than 90 minutes. The weekends provide the larger portion of the training hours, with a mix of conventional and non-conventional training structures; half the weekends include the 2nd swim for the week. Each week includes 1-2 days off.

Requirements: You should have a good base of an average of 5-7 hours of weekly training for the past four weeks. Going into this plan you should be able to:
  • Swim at least 2000 yards/meters
  • Bike at least 1 hour and 30 minutes
  • Run at least 1 hour and 15 minutes

You will build to:
  • 2600 yards/meters of swimming
  • 3 hours and 45 minutes of cycling
  • 2 hours 15 minutes of running

Your regular day off is Monday, your extra day of is Thursday. You’ll have a long bike-run (brick) or long run-bike (reverse brick) on Saturday, and you’ll have a long run, a second long ride, or a medium-distance brick on Sunday.

Our programs are designed for the age group triathlete who has a busy life with a full-time job, a family and/or other responsibilities. In this program, the longer workouts will be on the weekends, and the weekdays will consist of a single session (bike/run or swim/strength) totaling no more than 90 minutes. Brick workouts are present throughout the plan. One race simulation day is included in week 12. During the training plan, there is periodic testing to assess your fitness and adjust your training zones.

Our plans set YOU up for success. The main goal of this plan is to fully prepare you for race day.

Sample Day 1

Bike Benchmark Workout

Find a flat course with no stoplights/stop signs and few turns, or complete indoors on your trainer. Warm up for 20', including 4x20" builds with 40" RI. Then complete a 30' Time Trial. Press the lap button 10' into the TT. Note your average HR for the final 20'. Cool down for 10 minutes.

Sample Day 2

Swim Benchmark: Base Pace Test Set

WU: 300 swim
4x50 EZ / Fast (15" RI)
100 easy
10x100 on 5" RI
Swim 10x100 at your fastest sustainable pace on 5" rest - ideally this is swum as a send off set (e.g., 10x100 on 1:50, coming in around 1:44-1:46). Your send off can be set after your first 100 - add 7-10 seconds to your time for the first 100 to get to a round number (X:X5 or X:X0). Let me know what send off you used, and what you came in at for the 100s.

CD: easy 200 swim

Upon completing the workout, calculate your average 100 pace for the 10x100 set and use that to update your swim threshold pace (found in TrainingPeaks Settings) using the Distance/Time method.

Sample Day 3

Benchmark Run Workout

Find a mostly flat course with no stop signs/stop lights - or go to your local track. Warm up for 20', including 4x20" builds with 40" RI. Then complete a 30' Time Trial. Press the lap button 10' into the TT. Note the distance covered over the full 30', and your average HR for the final 20'. Cool down for 10 minutes.
