We use TrainingPeaks to deliver your plan – the world’s most popular endurance coaching platform. Free to use, TrainingPeaks is an online calendar that lets you record, track and analyze your training sessions.
It has a host of great features allowing you to get as in-depth as you like, including the ability to export your workouts to your training devices (Garmin, TrainerRoad etc) and follow them in real time.
TrainingPeaks enables us to set you in-depth training plans in a way that other formats cannot. Phil Mosley is a Certified Coach and one of the best-selling coaches on the platform.

As you can understand, some limits apply, like personalisation or analysis of your training, but for anything else relevant to your plan, we would love to help. You also have full access to our online help centre, with videos and articles to help you train effectively.
We have a huge range of plans that enables you to select one that best meets your goals, schedule and ability. If you’re not sure where to start, read on below for a quick overview.
What type?
Our Standard and Masters plans are designed to get you ready for your target event, while our Off-Season plans are designed to allow you to recover from a tough season whilst maintaining your well-earned fitness. Generally, Masters plans are designed for athletes over 40 years old, although plenty of younger athletes love them too. The workouts are just as tough as with our standard training plans, but with more scheduled recovery days. Some find it easy to carry on with a normal training load, while others need to change their approach to training.
What length?
For the best outcome, count back from your “A” target race date and simply choose a plan to fill that gap (you can still work in other, smaller races during your plan). Note that longer plans start easier and progress more gradually than shorter plans. The body responds best to constant, gradual progression with regular recovery periods, and that’s exactly what our plans are designed to give you!
What level?
Choosing the correct level will help you get the most out of your plan. Generally, if you’ve never done this event before or currently train up to a few times per week, you might consider a Beginner plan. Alternatively, if you’ve done this event many times before or currently train 5+ times a week, you might consider an Advanced plan.
But don’t worry too much – we also let you swap the level for free within 14 days of purchase, if you find it too easy/hard!
Visit the MyProCoach Help Center for further guidance and to contact our Certified coaching team.
Certainly! Our training plans allow you to easily swap a few days around each week to suit your availability. Or you can swap out a session, to attend a similar group workout instead. That’s fine. If you opt for TrainingPeaks Premium (from $9.92 per month) you can even drag & drop your workouts onto different days. We give a few recommendations on how to best do this in our help centre.
And you can also train for multiple events! Our training plans guide you up to your target “A” race, but it’s also good to include some “B or C” races along the way. Our help centre goes through the exact steps you should take to enable you to get full benefit, without detracting from your key focus

Your training plan (IM Intermediate, 12 wks) allowed me to improve my own record on IM70.3 by 25min to reach 4H51 at Les Sables d'Olonne and my IM record by almost 2 hours to reach 10H48 at Roth. I am so happy with those achievements that I now decided to try a marathon plan for the end of my season. Next year, I will target to qualify for IM70.3 world championship and will definitely use your plan again! Thanks, Alex << read less12 Jul 2019Chris SharkeyIRONMAN 70.3, December 2019Thank you! Just wanted to thank you for the training plan and your advice through the plan. I have just completed the Bahrain IRONMAN 70.3 and had a wonderful day. I smiled all the way through it.

For the first Year (2018) did IM Austria 10:03 My goal was to go sub 10, I think I failed because of weather (was hot day for running) and bit too much elevation gain on bike and nutrition. This Year (2019) I did the same plan 2nd year in a row And was able to fulfill my dream - going sub 10 Did Challenge Roth in 9:36 So thanks for the great training plan 🙂 Also in the process I went sub 3 in marathon (2:53) and two Years in a row was on podium in Latvian nationals in Olympic distance, and I did not do any special training for that, just this full distance plan (I did marathon in the middle of plan) Choose the right plan (that suits Your work, family and other commitments - I have 9am-6pm work and family), follow it and You will be FAST << read less23 Jul 2019
- Christina RoehrenbeckIronman 70.3 Luxemburg, July 2019Perfect plan for my first 70.3 I used Phil's Novice 70.3 plan (28 weeks) to prepare for my first ever 70.3 in Luxemburg.

My goal: finish with a smile. Being a slower athlete (sometimes THE slowest) I always struggled with finding a plan that would fit my needs: it would have to take my slower paces into account but still would have to prepare me for a race longer than 7 hours. It actually was my first plan I purchased from Phil. It worked out perfectly for me! Distances and duration, even of the longer sessions, were totally fine for me and when needed paces and the plan itself were adjustable to my needs. Still, I was training for a middle distance so there definetely is some work to do but it was totally managable, also in between my every day life and job. And after some ups and downs on race day I crossed the finish line in Luxemburg. << read less23 Jul 2019Kyle MiersmaIRONMAN 70.3 & 140.6, 2019Easy to follow and great IRONMAN results!!

Excellent guidance through 9 months of training led me to 9 hours 43 min IM finishing time. It was very motivating to see progress during several first months.

I liked the idea of a good long base section to get a strong foundation. The plan was great. Really easy to follow. I upgraded my Training Peaks account so that I could move workouts around during the week to fit in with a busy family life. I just ticked off the sessions one by one, week by week. Nothing more satisfying than ticking off all the sessions. As the event and other races got closer, their help was invaluable. They helped me swap sessions around to prepare me for the less important races, do it didn’t affect my fitness or ability to train effectively for the main event. And my questions were always answered quickly - even at the weekend when I wasn’t expecting a response until the following week! I loved the Strava club, blogs with great advice and social media feed in the run up to the race too. It was great to see how other people were training and feeling too. It’s a real community. Thanks to the plan and support I got to the start line injury free and not only completed the race but enjoyed it too! << read less25 Jul 2019David SchwanIRONMAN 70.3 for Masters, November 2019Very Good Plan/Holistic approach Only 5 weeks into the training plan, but love so far.
