Welcome to your Do3 triathlon training plan

You’re all signed up – great decision. Now we just need to connect your training and get you into the Do3 Hub. Follow these quick steps and we’ll take care of the rest.

Show video summary / transcript

In this short welcome video, Dave Knight explains what happens next now that you’ve bought a Do3 training plan: how to connect your TrainingPeaks account, download and use the Do3 Hub app, where to find your “Start Here” course and training notes, how to join the community spaces, and how to get help if you’re unsure about anything.

Total time: around 5–10 minutes. After that, we’ll apply your plan for you.

Step 1 · Vital

Connect your TrainingPeaks account

This is the most important step – it allows us to apply your training plan. Everything else is optional (but recommended) to get the most out of your support and resources.

1. Create or log into TrainingPeaks

If you don’t already have a TrainingPeaks athlete account, create one here. If you do, just log in.

Create / log into TrainingPeaks

2. Link your account to Do3

This gives us permission to add your sessions directly into your calendar.

Once this step is complete, we’ll apply your training plan to your account. You’ll see it appear in your TrainingPeaks calendar shortly afterwards.
