Western Heights, Dover | Register your interest

A community trail day like no other — set around the world’s largest Napoleonic fortress, the Western Heights Trail Races bring together runners, walkers, and canicross families for a full day of movement, music, and tired legs.

Whether you're chasing a podium or just out for the views, there’s a race (or walk) here for you.

Distances include:

• Mighty Miles – 1 & 2 mile children’s races

• 5K to 50K – Tough, scenic routes with punchy climbs and sweeping views across to France

• Walking category – Same course, same support, no rush

• Canicross friendly – Four paws welcome

With street food, music, and a proper festival atmosphere, this is more than a race — it’s a day out with the Hellfire crew.

THE GOVERNOR BACKYARD ULTRA

One loop. One hour. Until there’s only one left.

Welcome to the first — and only — Backyard Ultra to take place entirely inside the high walls of a former prison.

We hosted this event in 2024. It was massively popular — and we cannot wait to bring it back.

Who will be the last person standing to earn The Governor’s pardon?

THE GRAND ASCENT

One staircase. One day. One challenge that gets steeper every hour.
Western Heights, Dover | Register your interest

Buried deep inside Dover’s Western Heights is a hidden architectural monster — the UK’s only triple-helix staircase, originally built to get troops from the barracks down to the shoreline in a hurry.

Now it’s your turn to climb it. Again. And again. And again.

The Grand Ascent is simple to explain and tough to forget:
Climb the staircase as many times as you can within 24 hours.
The more you climb, the higher you rank.
Can you reach the height of Mount Everest?

This isn’t your usual race. It’s vertical, repetitive, and oddly addictive.

No shortcuts. No distractions. Just you, the stairs, and a challenge that keeps demanding more.

THE MOAT

One moat. Just the clock and your limits.

Set entirely inside the grassed moat of Dover’s Citadel Fortress, The Moat is a time-based ultra that asks one question — how far can you go when nothing changes but the clock?

The route is simple: a two-mile out-and-back, completely enclosed within the high walls of the Citadel’s moat. You choose your time limit — 6, 12, 24, or 48 hours — and run as far as you can before time runs out.

What’s your distance target?

If you’re drawn to quiet suffering and want to see what’s left when the distractions are stripped away, The Moat is calling.
