Her Trails Coaching
Ultra-Trail Kosciuszko 50km by UTMB
Program for Women
The Kosci50 takes you through alpine meadows, granite outcrops and snow gum forests across the rooftop of Australia. A 20-week Her Trails program builds the aerobic durability, climbing and descending strength, and fuelling skill this alpine course rewards.
The Course
Running the Kosciuszko 50km
The Kosci50 is Oceania's Alpine Ultra-Trail: granite outcrops, snow gum forests and open alpine meadows in the Snowy Mountains National Park. It is a genuinely runnable course, but the rolling elevation, altitude and changeable mountain weather add up over 50km.
This course rewards runners who pace with restraint early, fuel consistently, and keep moving efficiently through the rolling middle and final climbs.
The Course Demands
What the race asks of you
We train for the specific demands of an alpine 50km: sustained aerobic effort, rolling climbs and descents, altitude and weather exposure, and the fuelling and mental discipline to hold form over 6 to 9 hours.
Rolling Alpine Terrain
Constant undulation across the course asks for effort management by feel, not pace, and the strength to keep climbing well late in the race.
Altitude + Weather
Exposed alpine sections mean conditions can shift quickly. Sessions build weather-readiness, layering decisions and calm decision-making.
Fuelling for the Distance
A 50km alpine effort demands consistent fuelling from early in the race. We rehearse carbohydrate, sodium and hydration strategy on long runs.
Race-Day Confidence
Mandatory gear, pacing strategy and checkpoint logistics are trained specifically, so nothing on race day is unfamiliar.
Before You Begin
The Kosci50 is a serious alpine ultra distance. The 20-week build assumes you arrive already running consistently, with the endurance base to begin structured ultra preparation.
- Consistent running across recent months, ideally 4 to 5 sessions per week
- Recent experience with long trail runs, marathon training or ultra-distance preparation
- Willingness to commit meaningful time to long runs, back-to-back weekends and recovery
- Access to hills, trails or stairs for climbing and descending sessions
- Willingness to train fuelling, hydration and mandatory gear systems
- Medical clearance if returning from injury, illness, or extended time off training
