Turn up to the Kosci 100 prepared.
The Ultra-Trail Kosciuszko (UTK) by UTMB is one of Australia’s most iconic trail races — a stunning alpine adventure with challenging terrain, epic scenery, and an atmosphere you’ll never forget.
To help you rise to the challenge of the 100km distance, we’ve built a dedicated UTK100 training plan designed to get you to the start line feeling strong, prepared, and ready to enjoy the journey. With a race of this scale, it’s not just about logging the kilometres — it’s about training smart, building resilience, and arriving with the confidence that your body and mind are ready.
The UTK100 plan combines a 12-week base phase to establish a strong aerobic engine and muscular endurance, followed by a 16-week race-specific prep block that gradually increases your volume, elevation, and intensity. Every session has a purpose — helping you train consistently, avoid injury, and feel your best when it matters most.
Whether it’s your first 100km or you’re chasing a new PB, this plan sets you up for success at Ultra-Trail Kosciuszko.

What our members say
I attempted the KosciMiler in 2023 but had it called it at 130km. In 2024,
I came back stronger – both physically and mentally and finished my first
miler in 28 hours and 30 mins. It was a solid test of my endurance and a
great training run for the UTAMiler in May 2025. Now, I have a clearer plan
for how to improve and be even better prepared for the next race
Parker Liang
I really, really loved it. My first 100km, it was an epic adventure running in snow for the first part (ankle deep in some parts) and in places I’ve never been before, and the scenery was so beautiful. The volunteers were all amazing, and it was all very well organised. I spent the day after the race going up to the top of Kosci and I can’t imagine how different the event would be with that massive climb on a hot day, a different experience again! Highly recommend the event to anyone it was very enjoyable, and it’s a stunning part of Australia.

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.

Frequently asked questions
Is this program suitable for a beginner?
This program is suitable for someone who has been training consistently for at least 2 years and is able to comfortably run 20km regularly on hilly trails without injuries. If you can not, or have not, consistently included a 20km “long run” in your training program, you should consider training for the Kosci50. 16 weeks will not be enough time to prepare your body for this 100km 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.
