Turn up to the Kosci 50 prepared.
The Ultra-Trail Kosciuszko (UTK) by UTMB is an unforgettable experience — with breathtaking alpine views, world-class trails, and an electric race-day atmosphere that makes it truly special.
To help you make the most of it, we’ve created a dedicated UTK50 training plan designed to get you to the start line feeling strong, confident, and ready to thrive. Many runners dive into UTK training with loads of enthusiasm, but without a smart plan, it’s easy to overdo it or miss key elements of preparation. That’s why a well-structured approach is key.
Our UTK50 plan starts with a 12-week base phase to build your aerobic engine and strength foundation, followed by a focused 16-week race prep block that progressively sharpens your fitness for race day. It’s been carefully crafted to help you build consistently, stay injury-free, and arrive at the start line ready to deliver your best performance yet.

I also want to mention how instrumental your plans and online guidance have been to a big turnaround in my life and a refound love of the outdoors and running
Sanil Patel
I really appreciate everything I have learnt from you over the years. Really wish I had your help and knowledge when I was in my 20s over-training, getting injured all the time, peaking before orienteering races and believing I could eat whatever because I could just burn it off.
Tristram Miller
“When I joined my average pace for a 5km race was 6:53 min/km with elevation gain of 53m…
I recently did the 50km Coastal Ascent and my average pace was 6:55 min/km with elevation gain of 1454m.
Not bad I reckon! So, thanks again for your plans! ”

Frequently asked questions
Is this program suitable for a beginner?
This program is suitable for someone who has been training consistently for at least 18 months and is able to comfortably run 17km – 18km regularly on undulating terrain without injuries. If you can not run 17km regularly, you should consider training for a shorter race. The Kosci30 might be more suitable. 16 weeks may not be enough time to prepare your body for this 50km race distance without risking injury.
Can you help me train when I'm injured?
Probably, depending on your injury. We are very sorry to hear you are injured. We know how difficult that can be. If you have an injury that requires some rest from running, there are almost always some cross-training options available to help you maintain your fitness, strength, and sanity. By cross-training while you are injured, and including some simple strength, stretching and foam rolling routines, you will speed up your recovery time and ultimately make your return to running easier and more successful.rnrnYou can start our free 4 week cross training plan now for FREE. It will help you to identify appropriate exercises based on your injury type and recommend what cross training methods will work best for your injury. When you are ready you can start our 10-week return to running program or one of our run-specific rehab plans.
Can I start this program late?
You get immediate access to your training plan when you join. You can view the current week plus any previous weeks. We recommend that you start with a weekly volume that your body is currently able to cope with, which might mean starting on the beginner level before moving to intermediate a few weeks later.
