UTS Training: How to Prepare for a Mountain Ultra

Preparing for UTS means looking beyond the distance on the entry form. Long climbs, demanding descents and uneven ground can make a mountain race feel very different from a similar distance on smoother trails.

Your training should help you handle those demands while leaving enough recovery to absorb the work.

Train for climbing time

Weekly distance does not tell the whole story

Weekly distance does not tell the whole story when preparing for a mountain ultra. Consider how much time you spend climbing and whether your training includes sustained uphill efforts. Use local hills regularly and, where practical, arrange occasional outings on terrain closer to your race.
Practise purposeful hiking too. Being comfortable switching between running and hiking gives you more options when the gradient changes.

Prepare for the descents

It is easy to focus on getting uphill and overlook what comes afterwards.

Introduce downhill running gradually, starting with manageable slopes and controlled efforts. Build familiarity with the ground before chasing speed. A big downhill session can leave your legs more tired than expected, so account for it when planning the following days.

Rehearse the practical details

Use longer outings to practise with your race pack, footwear and food.

Use suitable longer outings to practise with your race pack, footwear and food. Can you reach your waterproof easily? Does your pack rub when fully loaded? Can you eat what you have packed while moving? Finding those answers in training gives you time to make changes. Follow the organiser’s current route information and mandatory kit requirements when preparing.

Make longer outings purposeful

You do not need to turn every weekend into a mountain epic.

You do not need to turn every weekend into a mountain epic. Decide what each longer session is for: steady time on your feet, climbing practice, terrain confidence or a kit and fuelling rehearsal. Build from your current fitness and allow easier periods. The goal is to arrive prepared, with energy left to race.
