FAQ's

These plans are tailored for athletes of all levels, from beginners to advanced, looking to maximize their performance. If you’re unsure of which level you are, get in touch!

The only thing you need is a trainingpeaks account and the usual swimming kit but to get the most out of your training plan, having the following would be ideal:

  • Compatible* smartwatch
  • Pull Buoy and Kickboard

 

*All common devices sync with trainingpeaks, check here to see if your device is compatible with the structured workout feature so you can follow your sessions on the go.

With years of experience coaching swimming, I understand that drills are very specific to the swimmer and can in many cases make technique worse. For this reason, plans focus on technique points rather than drills. The only ‘drill’ that you might come across in our training plans is sculling.

Training sessions are written in an optimal order for improvement, progression and recovery, but plans change and when they do you can move sessions across days and weeks with a premium training peaks account.

If you need to move things around but are not sure what is best, get in touch and I will help you out.

Sometimes, we have to miss a session, life gets in the way. Fortunately these plans are robust and consistency and efficiency will keep you progressing. Don’t fret over a missed session and don’t try and catch up either, you will still keep moving forwards.

You can adjust the schedule or swap sessions with a premium training peaks account; email support is available for advice if you’re unsure of what to do.

Every session includes detailed instructions and the rationale behind it. Feel free to email if further clarification is needed.

Improved endurance, better race-specific fitness, and confidence on race day. Results depend on how disciplined you are to the plan- it is designed to keep you motivated.

Our guarantee ensures that you are on the right training plan for you. If you find your plan is too much, too little, too hard or too easy, get in touch and we will swap you onto a more suitable plan.
