It’s no longer just anecdotal: science backs up what we’re seeing on the finish line. When it comes to extreme endurance, women often perform better over longer distances and durations. Why? 

If you're looking for a once-in-a-lifetime adventure that blends cultural immersion, physical challenge, and epic landscapes, Rat Race's Japan Sea to Summit should be top of your list. From the ocean edge to the sacred summit of Mount Fuji, this is more than a challenge, it’s a journey across the soul of Japan.

Here’s why the Ultra Tour of Arran is an unmissable challenge, and everything you need to know before you hit the trail. The Rat Race Ultra Tour of Arran (UTA) is Scotland at its wildest and most wonderful, a rugged, 2-day, fully-supported ultramarathon that takes you across an island dubbed “Scotland in miniature.” From glens and ridges to forest trails and coastal views, this is an ultra like no other.

Looking for an unforgettable endurance challenge in the Scottish Highlands? The Rat Race Coast to Coast is one of the UK’s most iconic multi-sport events, an epic adventure that takes you across Scotland from east to west, combining trail running, cycling, and kayaking in a single, unforgettable journey.

Taking on your first ultramarathon is intimidating, especially if you’re signing up solo. The distance is longer than anything you’ve likely tackled before, and the logistics can feel overwhelming. That’s why The Wall ultramarathon, a 70‑mile adventure along Hadrian’s Wall from Carlisle to Newcastle, is one of the best choices for first‑timers who want to test themselves on an iconic route without the stress of going unsupported.

Signing up for a 100-mile ultra has long meant navigating a maze of prerequisites: qualifying races, harsh cut-offs, vetting processes, and an unspoken expectation that only elite, ‘serious’ runners need apply. For years, 100 milers were treated as the exclusive domain of the 0.001%, those with perfect training logs, sub-elite marathon times, or enough free time and money to dedicate their lives to the trail. Until now.
