This 100k Ultramarathon training plan is designed for runners who are simply looking to comfortably complete their event.

With 6 months to prepare, we focus on very gradually increasing the weekly mileage at a manageable rate, so you don’t end up burning out.

Ideally you should be able to run 3-5 miles without stopping before you begin this plan, but you can choose to adopt a run/walk strategy too!

Who is it for?: First-time ultramarathon runners, runners who want to complete an ultra with limited time to train each week, runners who just want to focus on comfortably reaching the finish line.

How Long?: Six months, or 24 weeks. If your only objective is to complete your ultramarathon comfortably, and you have six months (or more) to prepare, this is the plan for you!

The plan includes some optional speed work, but this is only if you’re comfortable and can squeeze it in – the objective is to get the required mileage in. It includes 3 mid-week runs, to be performed at a comfortable pace, and one long-slow run each weekend to build your max mileage. The plan includes one cross-training day per week and two rest days.
