How hard is the Milford Track, and how do you train for it?
Four days, 53.5 km and one big day. Here is what each day really asks of your legs, and the training that covers it.
By Nathan Gee, Peaksted coach · Updated · 6 min readMost people look at the Milford and worry about the climb. It is the way down that does the damage. If you only train one thing, train the descent.
The good news: it is a very trainable walk. Strong legs, six-hour days and a bit of practice at doing it again tomorrow cover almost all of it.
Moderate overall, with one hard day. Day three climbs more than 500 m to Mackinnon Pass and drops around 1,000 m in 6 to 7 hours. The other days are gentle but long.
The Milford in numbers
One way, three nights, three huts. Figures follow the Department of Conservation.
- 53.5 kmone way, over four days
- 19 to 20 hof walking, all in
- 500 m upto Mackinnon Pass, day three
- 1,000 m downoff the pass, same afternoon
- 9,000 mmof rain a year at the wettest
- 1,154 mthe highest point, Mackinnon Pass
Three long days and one easy one
The bar is hours on your feet. Day three is dark because of what is in it, not how long it is.
Some maps and older guides show 16.5 km and 14 km for days two and three. DOC’s current page lists 17.5 km and 13 km.
Four things, and what to do about each
Pick one. Each says why it matters and what to practise.
The way down is the hard bit
Everyone worries about the climb to the pass. It is steady and well made. The descent is what catches people: your quads act as brakes for thousands of steps, on legs that have already climbed.
- Slow step-downs3 sets of 6 to 8 each leg, three seconds to lower. Twice a week for six weeks or more.
- Walk down on purposeFinish hill walks by walking down, not driving down. Short and often beats one big day.
- Calves and glutesCalf raises and glute bridges, 3 sets of 12 to 15, keep the knees happy on steep ground.
Three days of 5.5 to 7 hours
None of the gradients are hard. The test is time on your feet: days two, three and four are each 5.5 to 7 hours, around 19 to 20 hours of walking in total.
- One long walk a weekBuild up by about 10 minutes a week until you reach three hours, with snacks and your boots.
- Easy paceIf you cannot chat in sentences you are going too hard. Most of your walking should feel easy.
- Hills when you canOne steady hill or stair session a week keeps the engine honest.
It is a very wet place
Fiordland gets up to 9,000 mm of rain a year. In heavy rain the Clinton and Arthur valleys can become impassable, and DOC can close sections. Wet kit is heavier, cold legs are slower and people eat less.
- One wet sessionDo a proper walk in the rain before you go, so waterproofs and wet boots are not a surprise.
- Dry layer for the hutKeep one full set of clothes in a dry bag, and never wear it on the track.
- A flexible planCheck DOC alerts the night before and keep a spare day if you can.
Four days in a row
Day three is in the middle: you climb, descend and then walk 18 km the next morning. Recovery between days matters as much as the fitness you arrive with.
- Back-to-back walksA long walk on Saturday, then 45 easy minutes on Sunday. Tired-legs practice.
- Your real packFood, layers and water. Add weight gradually and check the hip belt.
- Fuel on a scheduleEat something small every hour. It matters on the long, flat days.
How long have you got?
Pick the time you have before you walk. Each one ends with the support that fits it.
You can build slowly, which is the kind way. Spend the first month on easy walking and two short strength sessions, then add the descents.
- Weeks 1 to 4: three easy walks and two strength sessions a week
- Weeks 5 to 8: add a weekly hill walk and slow step-downs, long walk to 2 to 3 hours
- Weeks 9 to 12: back-to-back days with your pack, one wet session, then an easy last week
Enough if you can already walk a couple of hours. Keep it simple and put the effort where the Milford asks for it.
- Weeks 1 to 3: easy walking, two strength sessions, find your base
- Weeks 4 to 6: long hill walk weekly, step-downs, one stair session
- Weeks 7 to 8: one back-to-back weekend with your pack, then taper
Do not cram. Protect your legs, practise the way down a little and arrive fresh.
- Two short strength sessions a week with slow step-downs
- One long walk, then an easy walk the next morning
- Wear your boots and pack so nothing is new on day one

How hard is the Milford Track?
Moderate overall, with one hard day. Day three climbs more than 500 m to Mackinnon Pass (1,154 m) and then drops around 1,000 m in 6 to 7 hours. The other days have gentle gradients, but they are long and often wet.
Which day of the Milford Track is the hardest?
Day three, from Mintaro Hut to Dumpling Hut. It is the shortest of the long days at 13 km, but it has the climb to Mackinnon Pass and a long, steep descent.
How fit do you need to be for the Milford Track?
Comfortable walking five to seven hours, climbing steadily, coming down with control and doing it again the next morning. It is durability more than athletic fitness.
How long should I train for the Milford Track?
Eight to twelve weeks is a good window if you walk occasionally, and more if you are starting from scratch. If you already hike regularly, four to six weeks of specifics is enough.
Is the Milford Track dangerous in rain?
It is a very wet place, with up to 9,000 mm of rain a year. In heavy rain the Clinton and Arthur valleys can become impassable and DOC can close sections, so check alerts and keep a flexible plan.
Do I need trekking poles for the Milford Track?
Many walkers find them helpful on the long descent. If you plan to use them, practise in training so the technique is automatic.
What if I cannot get a booking for the Milford Track?
Routeburn and Kepler are the nearest Fiordland walks, with a similar demand on your legs. Our Milford vs Routeburn vs Kepler guide compares them.
The free readiness check takes about three minutes and shows which of seven physical areas to work on first.
