The Three Faces of Dorset Trails

The South: The Technical and Steep Jurassic Coast

"This is where the 'Dorset Vertical' lives. Running the limestone cliffs between Lulworth and Weymouth is a lesson in technical footwork. Expect steep, jagged climbs and rapid-fire descents that test your ankle stability and eccentric leg strength. It’s brutal, beautiful, and the ultimate training ground for ultra-runners."

The East: The Purbecks & Studland Sands

The South: The Technical and Steep Jurassic Coast

"For a faster, more 'flowy' experience, the Purbecks offer undulating ridgelines with views of Corfe Castle. The challenge here is the variety; you'll transition from springy turf to deep, energy-sapping sand around Studland. It’s the perfect place to work on your gear-shifting and sustained aerobic power."

The North: The Chalk Downs & Blackmore Vale

The West: Bridport, Portland & the Ridgeways

"Heading inland, the North Dorset Downs provide long, rolling climbs on ancient chalk tracks. These trails are less about technical 'scrambling' and more about maintaining a rhythm. Warning: the Blackmore Vale valleys turn into a thick, 'clay-trap' mud in winter—this is where we test your mental toughness and your choice of lugs!"

The West: Bridport, Portland & the Ridgeways

"West Dorset is where you find the true 'raw' character of the coast. Running the Isle of Portland is a must in high winds, while the Chesil Beach connection requires unique power to handle the shifting shingle. As you move inland towards Beaminster and the Abbotsbury Ridgeways, the terrain opens up into long, sweeping climbs through rolling farmlands. These are the miles that build your 'diesel engine'—sustained aerobic efforts with some of the most dramatic views of the West Bay cliffs"

The Dorset Trail Intel

Absolutely. While Dorset lacks alpine peaks, the relentless vertical gain of the South West Coast Path provides the perfect 'reps' for mountain endurance. Having completed two 170km UTMB finishes and the 170km UTS Snowdonia, I’ve proven that the constant 100m–200m climbs between Lulworth and West Bay perfectly mimic the cumulative fatigue of the Alps


For those new to the trails, the Studland Peninsula and Old Harry Rocks offer the best introduction. These trails are relatively 'flowy' with manageable underfoot conditions compared to the technical limestone of the west. It’s the ideal spot to practice transitioning from road to trail without the extreme verticality of the central Jurassic Coast


The 210+ mile Hardy Way is a significant logistical challenge, crossing diverse terrains from the North Dorset Downs to the coastal ridgeways. As the current FKT (Fastest Known Time) holder, I recommend breaking the route into sectors. The inland sections of the North and West require navigational prowess than the coastal paths, and each phase presents challenging underfoot conditions depending on the weather.


Dorset winter running is defined by one thing: Mud, clay and sapping grassy fields. Between November and March, you need a shoe with at least 5mm-6mm lugs to maintain traction on the inland farmlands and chalk downs. Additionally, the coastal winds can be brutal; a high-quality hardshell and knowledge of the Lulworth Range firing times are essential for a safe, successful winter training block


About Your Coach: The Hardy Way Expert

Richard O'Connor - Founder Madmule Trail

'I don’t just coach on these trails; I’ve lived them—holding the Fastest Known Time (FKT) for the 220-mile Hardy Way and successfully completing the world’s most iconic mountain races, including two 170km finishes at UTMB and the brutal 170km UTS Snowdonia. I’ve spent years proving that Dorset’s relentless vertical gain and technical coastal paths are the perfect training ground for the toughest ultra marathons on earth. My coaching brings this elite mountain experience to our local trails, helping you master the terrain—whether you're tackling your first 10k or your 100th mile.'
