The world has dozens of endurance rides, adventure races, and historic horse events. Most are interchangeable. A handful are not.
These are the eight events Saddl thinks every serious rider should know about, split into three groups. UK events you can realistically enter. International ultra-endurance races for the few who train for them. And one Italian medieval spectacle that you can only watch.
This is not a comprehensive directory. It is an editorial selection: the events with the strongest character, the genuine challenge, and the lasting cultural weight.
Group 1: UK events you can actually enter
Man v Horse Marathon
Where: Llanwrtyd Wells, Powys
When: 13 June 2026
Format: 22-mile cross-country race, runners vs horses
The Welsh oddity born of a 1980 pub argument. About 1,000 runners take on roughly 50 horses and riders over 22 miles of hill country. The horses usually win. Twice in 45 years, a human has beaten the entire equestrian field. The most accessible event on this list and the one your non-horse friends will actually understand.
The Golden Horseshoe Ride
Where: Exford, Somerset (Exmoor National Park)
When: 23 to 24 May 2026
Format: Multiple endurance classes, 25km to 160km
The UK''s oldest endurance ride, run since 1965 by Endurance GB. Classes for every level: the 25km Bambi pleasure ride is open to anyone with a fit horse, while the 160km two-day flagship is widely considered one of the toughest endurance rides in Europe. The right entry point to UK endurance.
Royal Windsor Endurance Ride
Where: Windsor Great Park, Berkshire
When: 15 May 2026
Format: FEI international and national graded endurance, 40km to 120km
Returns to the calendar in 2026 alongside the Royal Windsor Horse Show. The most prestigious one-day endurance setting in the UK. FEI classes for international qualification, plus national classes for grassroots and intermediate riders. Course runs through Windsor Great Park including sections of the Long Walk.
Red Dragon Festival of Endurance
Where: Royal Welsh Showground, Builth Wells, Powys
When: Early October 2026
Format: 30+ endurance classes over 3 days, 25km to 160km
The traditional close of the UK endurance season. Cambrian Mountain terrain, October weather, and the Home International team event between England, Scotland, Wales and Ireland. The natural bookend to a season started at the Golden Horseshoe.
Group 2: International ultra-endurance races
These are not for the casual entrant. Each requires documented endurance experience, significant cost, and 12 to 24 months of dedicated training. We include them because they''re the references against which UK endurance is calibrated, and because a small number of UK riders successfully take them on every year.
The Mongol Derby
Where: Mongolian Steppe
When: August annually
Format: 1,000km on 25 semi-wild horses, 7 to 10 days
Entry: ~$18,000 (2026), $19,000 (2027)
The world''s longest horse race. Recreates Genghis Khan''s 1224 postal system. Riders change horses every 40km at one of 25 horse stations across the Steppe, sleeping with herding families or camping out. The benchmark ultra-endurance race against which every other is measured.
The Gaucho Derby
Where: Patagonia, Argentina
When: February annually
Format: 500km self-supported across mountain terrain, 10 days
Entry: ~$19,000 (2027)
The Mongol Derby''s younger and harder sibling. Half the distance, but the technical Patagonian terrain (high mountains, dense forest, river crossings) and the self-supported camping make it widely regarded as the tougher event. Run by the same team. Run in late summer in the Southern Hemisphere.
The Tevis Cup
Where: Lake Tahoe to Auburn, California
When: July/August annually
Format: 100 miles in 24 hours, single day
Entry: Several hundred dollars (plus qualifying rides)
The American gold standard for endurance riding, run since 1955. 100 miles across the Sierra Nevada in a single day, finishing under moonlight for most riders. The Western States Trail. The Haggin Cup (awarded to the best-conditioned top-ten finisher) is generally considered more prestigious than the winning trophy.
Group 3: The one to watch
The Palio di Siena
Where: Siena, Italy
When: 2 July 2026 and 16 August 2026
Format: Bareback race, three laps of Piazza del Campo, ~90 seconds
Twice a year, ten bareback riders representing ten of Siena''s 17 medieval contrade race around the city''s sloped main square in front of 50,000 spectators. It lasts 90 seconds. It has run essentially unchanged since 1644. You cannot enter. You can only watch. For any rider with a serious interest in the cultural history of horse sport, it is worth flying for.
How to use this list
If you''re newer to riding and want a goal: aim for the 25km pleasure ride at the Golden Horseshoe, then the Man v Horse equestrian class, then a graded Endurance GB ride. Three years, three real achievements.
If you''re an experienced endurance rider working towards bigger things: the ladder runs through Endurance GB graded rides (80km, 120km, 160km) and on to the FEI Royal Windsor and the Tevis Cup if you can hire a qualified American horse.
If you''re looking for the once-in-a-lifetime adventure: the Mongol Derby and Gaucho Derby require commitment that most of us won''t make, but a small number of UK riders make it onto the start line every year.
If you''re looking for cultural pilgrimage rather than personal achievement: book yourself onto a Tuscan riding holiday around the August Palio and combine the riding with a balcony seat in Siena.
Saddl''s commercial honesty
We''ll be straight with you. None of the events on this list pay Saddl an affiliate commission for sending you their way. Mongol Derby, Tevis, Royal Windsor, Golden Horseshoe and so on are fixed-price participatory events with direct entry processes. We''ve published this list because it''s genuinely useful editorial, not because there''s a revenue line behind it.
Where we do think a commercial recommendation makes sense, it''s in the riding holidays that sit alongside these events. A trip to Siena pairs naturally with a Tuscan riding holiday. The Mongol Derby experience without the race is a Mongolian riding holiday. The Gaucho Derby idea without the race is an Argentine estancia ride. These we do route through affiliate partners we trust.
