The MacLehose Trail: A Runner's Guide

MacLehose Trail | 100km | Pak Tam Chung to Tuen Mun | FKT: 10.5h

Stretching 100 kilometers from Pak Tam Chung in Sai Kung to Tuen Mun, the MacLehose Trail is one of - if not the - most iconic long-distance hiking trails in Hong Kong. This legendary trail traverses much of the New Territories, offering a diverse mix of terrains, from lush forests and rugged ridges to serene reservoirs and coastal paths. With over 5,000 meters of elevation gain, it’s a true test of endurance.

One of many highlights of the trail is its passage over Tai Mo Shan, Hong Kong’s highest peak at 957 meters, where panoramic views reward those who make the climb.

We've run the MacLehose Trail before. It's tough, but not as tough as the much shorter, but more technical Wilson Trail! Here's our MacLehose Trail Runner's Guide.

Our Experience Running the MacLehose Trail

As two Hong Kong-based runners, we decided to take on the MacLehose Trail in its entirety, starting at 3 AM in the dark from Pak Tam Chung and finishing 18 hours later, around 9 PM in Tuen Mun.

We chose a weekend in November when Hong Kong’s cooler weather and lower humidity make for ideal running conditions. It was a sunny but cool day, ideal for running in shorts and a T-shirt. Other than that, we carried a hydration bladder. One of us also used hiking poles for extra stability.

To get to the start of the MacLehose, we took a taxi from Hong Kong Island to Pak Tam Chung, dropping off food supplies at the public restroom near Sai Sha Road Barbecue Site (the end of Section 3 / start of Section 4) along the way. We hid our cooler bag which contained food and water, behind the trees just by the restrooms and found it in perfect condition when we arrived.

As we started running in the middle of the night, the restaurants/kiosks in Sai Kung were still closed, so making a first fuel stop at the end of Section 3 was our best option. We reached the spot just in time for breakfast, and this stash was our first big meal.

We also had friends meet us at the Monkey Mountain Public Toilet at the start of Section 6 to bring more food, and we refueled with hot cup noodles at Sha Tin Pass on Section 5 and the Tai Mo Shan kiosk on Section 8. Of course, we carried our own gels, water, and electrolytes to stay hydrated and energised throughout the run.

Our nutrition plan was simple: aim for at least 100 calories per hour, with a slightly larger meal every 3 hours. We also carried salty sticks/electrolytes, which we ate approximately every 90 minutes to preempt cramping.

Sticking to this plan helped us maintain energy levels and avoid hitting the dreaded "wall." Since this was our first 100-kilometer run, we prioritised finishing over speed, which made the experience surprisingly relaxed and enjoyable! For example, we took our time during meal breaks, sitting down to rest our legs.

One of my favorite pieces of gear was my hiking poles. They made the steep climbs up Needle Hill and Tai Mo Shan much more manageable. The poles helped distribute some of my weight, reducing strain on my legs during the toughest ascents. Poles aren't for everyone, and it takes practice to get used to them. But if you know how to use them effectively, they are very useful.

The final stretch of the MacLehose, running the last two sections in the dark, was undoubtedly the most challenging part.

Neither of us had run these sections before, so we didn't know what to expect. You think you are near the finish line, and even though they’re mostly on runnable roads, the 20-kilometer distance felt grueling after we had already covered 80 kilometers!

Overall, discipline and staying focused were the keys to success: following our meal plan, setting a comfortable pace from the very start (even if we thought we could go faster), and keeping our eyes on the prize, running the entire trail without quitting.

What Makes The MacLehose Trail Unique?

The MacLehose Trail is one of Hong Kong’s most iconic and diverse running routes. At 100km it is a true test of endurance that introduces hikers and runners to some of the best trails in Hong Kong. But each vista has to be earned. It's more than 5,000 meters of elevation gain require a very good level of fitness for those who attempt to conquer the trail in one go.

The MacLehose Trail takes you through some of Hong Kong’s most breathtaking landscapes. From the beautiful beaches of Sai Kung to the rugged ridges of Tai Mo Shan, Hong Kong’s highest peak at 957 meters, the trail offers panoramic views of reservoirs, coastline, and rolling hills.

It features everything from steep climbs and technical descents to flat, runnable paths. Each of its 10 sections presents a different challenge, keeping the experience fresh and engaging. It also passes through areas rich in history, such as the Gin Drinkers Line, a series of WWII-era defensive fortifications.

Despite its remote feel, the trail is easily accessible from the city, with multiple entry and exit points along the way. This makes it ideal for both long-distance runners and those looking to tackle shorter sections.

Last, the MacLehose is a popular route for popular races and events. Events like the Oxfam Trailwalker, a team challenge, and HK100 Ultra Marathon bring together runners and hikers from all walks of life!

For those living in or visiting Hong Kong, exploring the MacLehose Trail is an activity not to be missed!

How Fast Can You Run the Entire MacLehose Trail?

The fastest known time (FKT) of the MacLehose Trail was set by local Hong Kong trail running legend Ho-Chung Wong (yes, the same Ho-Chung Wong, who holds the record for the 298km HK4TUC challenge). It took him ten hours, 38 minutes and 8 seconds. For comparison, the fastest known time for the 78km Wilson Trail is nine hours, 59 minutes, and 16 seconds. The Wilson is much more technical than the MacLehose or put differently, for those seeking a more "beginner-friendly" challenge, the MacLehose Trail is the better trail to start with as it is more runnable.

If you are not an elite runner with calves of steel, expect to spend 20 or more hours to complete the entire MacLehose Trail. At the annual Oxfam Trailwalker, a charity event where teams of four run or walk the entire trail, any time below 24 hours is considered a strong result and the official cut-off is 48 hours!

For average hikers, turning the MacLehose into a multi-day adventure is also a great option. For your options and recommended routes, fuel points and camps, we recommend visiting Thru Hiking Hong Kong's guide to the MacLehose.

Is There a Race On The MacLehose Trail?

There are several options for those wanting to run the MacLehose Trail as part of a running competition. Oxfam Trailwalker, a team event, is one of Hong Kong's most popular hiking events. Though it is a charity event, the top teams compete to break the course record every year.

The HK 100 Ultra is another highly competitive and well-organized running event that follows the MacLehose Trail.

Practical Advice for Hiking the MacLehose Trail

You don't need to have hiked every section of the MacLehose Trail before attempting it in its entirety. However, know where to find water refill stations, food stops, and checkpoints (if in a race) along the route. Some sections are remote, so plan ahead and carry enough supplies to stay hydrated and energized.

2. Pick the Right Season

The best time to hike the MacLehose Trail is during autumn and winter (October to March), when the weather is cooler and less humid. Avoid summer months due to high temperatures and the risk of thunderstorms.

3. Make Use of Its Accessibility

The trail’s multiple entry and exit points make it easy to break your hike into manageable sections or to meet withfriends or a support crew for refueling, a change of clothes or extra motivation!

If you’re feeling exhausted, don’t push yourself—stop and return another day.

Most importantly, enjoy the journey and stay safe!

What's The Best Time of The Year to Run The MacLehose Trail?

The best time to run the MacLehose Trail is during the cooler months, typically from October to March with November and December being our favourites.

This period offers milder temperatures, lower humidity, and more stable weather conditions, making it ideal for long-distance running. It’s no coincidence that most of Hong Kong’s major trail races, such as the HK100 Ultra Marathon and Oxfam Trailwalker, are scheduled during this time.

Avoid attempting the entire trail in summer (June to September), when Hong Kong experiences intense heat, high humidity, and the risk of thunderstorms or typhoons. These conditions can make running not only uncomfortable but also dangerous, especially on exposed sections of the trail.

By planning your run during the cooler months, you’ll enjoy a safer and more enjoyable experience, allowing you to fully appreciate the stunning scenery and challenging terrain of the MacLehose Trail.
