Blenheim Palace Triathlon: A Historic and Scenic Experience
The Blenheim Palace Triathlon blends history, atmosphere, and smooth race flow. You swim in a calm lake inside the palace grounds, then ride closed roads through rolling parkland, and finish with views of the grand stately home.
This race works for many levels. Sprint and super sprint options make it friendly for first-timers. The well-marked course, big crowds, and helpful volunteers keep nerves low and confidence high. If you’re more experienced, you’ll still enjoy sharp logistics and fast transitions.
Timing helps too. It usually runs in late spring, so you can test early fitness after winter training. Many athletes use it as a tune-up before larger summer events like the London Triathlon or Ironman Leeds. The festival feel (music, food stalls, and supporters) turns race day into a full experience.
The bike course features short rises and sweeping bends. It rewards steady pacing rather than surges. The run is on smooth paths with gentle rollers, so you can settle into a rhythm and kick late. Wave starts keep the swim calm and reduce congestion in T1.
Practical notes: parking and shuttle options are signposted, and the venue handles big fields well. Spectator spots near the lake and finish line make cheering easy. If you like a race that mixes sport with British heritage, this one deserves a spot on your list.

London Triathlon: Big-City Buzz on Fast, Closed Roads
The London Triathlon is the UK’s biggest city race. It runs from the ExCeL London hub with a swim in Royal Victoria Dock, a flat bike on closed roads, and a lively run packed with supporters.
You start with a sheltered open-water swim beside the skyline. Sight lines are clear, and wave starts keep things smooth. Kayaks and pontoons help you feel safe from the first stroke.
Transition happens inside the ExCeL, so you get wide aisles, good lighting, and easy wayfinding. Racks are numbered, and the floor is even underfoot. It’s ideal if you want a stress-free T1 and T2.
The bike course is flat and fast. Long straights reward steady power and clean lines through corners. You’ll see the city fly past (Docklands, riverside roads, and bridges) while marshals manage flow at every turn.
The run is looped, crowd-friendly, and easy to pace. You’ll pass music points and announcers often. That steady buzz helps you hold form when the legs start to fade.
It’s beginner-friendly but also great for a PB. You can choose super sprint, sprint, or standard (Olympic) distance. The layout supports big fields, so you get energy without chaos.
Logistics are simple. The DLR stops right at ExCeL. Bag drop is close to the start. Spectators can move between the dock, transition, and finish with little walking.
Want a weekend of racing? The mass-participation event pairs well with London’s pro showpiece, the London T100 Triathlon. You get the thrill of elite speed one day and your own big moment the next.
If you like clean lines, quick splits, and city energy, this race is your match. The course rewards calm pacing, tidy transitions, and a controlled final kick. It’s big, fast, and unforgettable.
Note: Brands and sponsors change over time. Check the official site for current schedules and categories. Some waves sell out months in advance.

The Dorney Lake Triathlon is built for speed. You race at Eton Dorney, the flat, sheltered rowing lake used during the London 2012 Games. That means calm water, smooth paths, and closed laps that make pacing simple and steady.
This course is a confidence booster. Sight lines are clear, corners are wide, and there are few surprises. If you want a clean swim and a fast bike, this venue delivers. It’s also a beginner-friendly triathlon thanks to easy parking, short walks to transition, and a looped layout that keeps you close to support the whole time.
Chasing a personal best? The bike is about holding even power rather than punching up hills. The run hugs the water on flat paths, so you can lock into goal pace and focus on cadence. Lap markers and frequent aid help you manage effort without overthinking.
Race options are flexible. You’ll find super sprint, sprint, and standard-distance starts across different weekends.

The Croyde Ocean Triathlon is one of England’s most striking races. Set along the North Devon coast, it pairs natural beauty with raw physical challenge. The event has earned a reputation as one of the toughest Olympic-distance races in the country.
The swim takes place in Croyde Bay, a surf beach known for rolling Atlantic swells. Depending on the day, conditions can be calm or testing. If you’re used to lake swims, the salt water, currents, and chop make this a whole new experience. Strong sighting and comfort in waves are must-haves here.
The bike course is hilly and technical, with short climbs that bite and descents that demand focus. Narrow country lanes add to the difficulty, but they also provide views of green fields and rugged cliffs. It’s a ride that keeps you honest. Steady pacing and careful handling beat brute force.
The run might be the hardest part. It follows coastal paths, sandy stretches, and steep trails overlooking the sea. Legs feel heavy, lungs burn, but the scenery distracts from the grind. It’s not the place for PBs—it’s a course built for pride and grit.
This isn’t a race for beginners. It’s best suited to confident swimmers and athletes who enjoy technical, challenging terrain. That said, the atmosphere is friendly and welcoming. The triathlon community here is tight-knit, with locals cheering loudly along the course.
If you want a triathlon that pushes limits while rewarding you with unforgettable views, this is it. Few events combine natural landscapes and raw endurance quite like Croyde. It’s not just a race—it’s an adventure by the sea.
Belvoir Castle Triathlon: Racing in Regal Surroundings
The Belvoir Castle Triathlon offers a race setting that feels straight out of a storybook. Located in Leicestershire, the castle and surrounding parkland provide a dramatic backdrop for one of England’s most atmospheric triathlons.
The swim unfolds in the estate’s lake, which is calm and well-contained—ideal for athletes who prefer a controlled environment over unpredictable seas. The water is sheltered, giving beginners confidence, while still offering the open-water feel that seasoned triathletes crave.
On the bike, rolling countryside roads dominate. The course mixes fast stretches with steady climbs, rewarding consistent pacing and power management. Road conditions are good, and marshals are well-placed, keeping navigation simple even with the winding country lanes.
The run takes athletes through parts of the castle grounds and nearby trails. The mix of gravel, grass, and tarmac keeps things varied underfoot, and the views are nothing short of spectacular. Running past historic stone walls and manicured fields gives this race an unforgettable character.
What sets Belvoir apart is its balance. It’s a challenging course, but it’s not extreme. That makes it a strong choice for athletes building toward bigger targets like the London T100 Triathlon or preparing for a later-season UK Ironman 70.3. For beginners, shorter distance options are available, making it approachable without losing the sense of occasion.
Practical touches add to the appeal. The castle grounds offer plenty of space for parking, family spectating, and post-race relaxation. The atmosphere is both professional and welcoming, attracting a mix of first-timers and experienced triathletes chasing a memorable venue.
If you’re looking for a race that combines English countryside charm with solid triathlon organisation, Belvoir Castle is a standout. It may not have the sheer size of London or Bolton, but it delivers something rarer—a perfect blend of history, scenery, and sport.
