“Chris at Efficient Endurance provided a 10-week training plan that worked brilliantly! The plan was flexible, syncable to my watch, and kept training varied and engaging. I enjoyed the structured sessions, especially the zone 2 runs, which were surprisingly relaxing.
The plan was easy to adjust around life events, and missing a session didn’t disrupt my progress. Chris offered fantastic guidance and support, answering all my questions and boosting my confidence. Thanks to this plan, I not only improved but also enjoyed the process. Highly recommend and excited to follow it again for renewed running purpose!”

Most likely. Plans that have strength sessions included use weights such as dumbbells, barbells, kettlebells and cable machines. You don’t have to do these sessions but they add another dimension to your training that running alone can not do.

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.
