Recurring Marathon races near Portsmouth

Running Grand Prix Goodwood October

New Forest Xmas Trails

New Forest Xmas Trails begins and ends at Holmesly Campsite in Bransgore, situated on the boundary of the New Forest National Park. This event, organized by BigFeat Events, offers winter off-road running with 15 km, 30 km, marathon, and 50 km distances. All races are single-lap courses that are fully marked. The event is presented as a Christmas trail-running festival and a final significant run prior to the holiday period. The courses depart from the campsite, venturing onto New Forest heathland and woodland, where winter conditions are an intended aspect of the challenge. The routes are characterized as demanding yet traversable, suitable for runners seeking authentic trail conditions without a multi-lap structure. BigFeat states the event was conceived by trail runners for trail runners, and the practical arrangements include complimentary hard-standing parking at Holmesly Campsite.

Portsmouth Coastal Waterside Marathon

The Portsmouth Coastal Waterside Marathon is a winter race weekend on England's south coast, centered on the Southsea seafront in Portsmouth. Participants can select from a marathon, half marathon, and shorter distances like 12K. Some editions of the series also feature a 50K ultra. The courses are flat, incorporating promenade, waterfront paths, coastal tracks, and multi-terrain sections, rather than being purely road races. The marathon begins seaside at Southsea, proceeding out and back towards Hayling Island. The route traces the edge of Langstone Harbour and other shoreline segments around Portsmouth. Runners will find expansive views across the Solent, extensive harbour running, well-supplied aid stations, and finish medals. The event embraces its winter timing with a festive atmosphere, and the broader Southsea event schedule includes fireworks over Southsea Common.

Running GP at Goodwood Motor Circuit February 2027

This winter marathon takes place at Goodwood Motor Circuit. Runners complete 26.2 miles on the closed racing circuit typically used for motorsport. The course is flat, situated at the foot of the Sussex Downs. Its appeal lies in offering a measured marathon on smooth circuit roads, distinct from a point-to-point road race through town streets. The marathon is included in the Goodwood House Running Grand Prix series, which also features half marathon, 10k, and 5k races. This format benefits mixed groups, allowing marathon participants to run alongside friends completing shorter distances, all within the Goodwood venue.

BigMud Trails begins and ends at Queen Elizabeth Country Park in Hampshire. Runners immediately face a steep ascent up Butser Hill, the highest point in the South Downs. This is a winter trail event held in the Meon Valley, offering 50K, marathon, and 16-mile distances on single-lap courses within the South Downs National Park. The route includes undulating terrain, woodland paths, sharp ascents, fast-running stretches, and significant mud. Butser Hill is tackled twice before the finish line at its base. BigMud represents the Earth race in the Classic Element Trail Series, a quartet of events themed around Earth, Water, Fire, and Air. This event is now in its sixth year. The clearly marked course, provision of aid stations, and the start and finish being at the same location simplify logistics. However, the challenging terrain is the primary attraction for participants seeking a demanding race over a flat, quick course.

BigMud Trails (EARTH)

BigMud is the Earth race in the Classic Element Trail Series, a collection of four trail events themed around Earth, Water, Fire, and Air. It starts at Queen Elizabeth Country Park in Hampshire, offering three single-lap options: a 50K ultramarathon, a marathon, and a 16-mile race. The event occurs early in the series, embracing muddy winter trail running over road speed or flat pacing. The routes venture into the Meon Valley and traverse the rolling hills of the South Downs National Park. Every distance involves the 518ft ascent to Butser Hill, the highest point in the South Downs, which runners climb twice before returning to Queen Elizabeth Country Park at the hill's base. The race is in its sixth year, does not permit canicross entries, and requires each runner to carry a minimum of 500ml of fluid, with hydration vests frequently used and handheld soft flasks permitted.

Larmer Tree Marathon, 20 Miler, Half Marathon & 10K

The Larmer Tree races start and finish at Larmer Tree Gardens on the Rushmore Estate, with spring trail races across the Wiltshire Downs. The series is family friendly and offers several distances: 7 miles, 10 miles, half marathon, 20 miles, and marathon. Dog-friendly 7-mile and 10-mile options are also scheduled. The routes use the private Rushmore Estate grounds, giving the event a country-estate feel. Runners should expect hills, and the ground can be muddy after wet weather. Shorter routes are suitable for newer trail runners, while the half marathon and 20-mile races are good for those building toward marathon season. Larmer Tree Gardens has been described as one of Britain’s poshest race venues, an unusual base for a muddy spring trail weekend.

Larmer Tree Marathon, 20 Miler, Half Marathon

The Larmer Tree race series takes place at Larmer Tree Gardens on the Rushmore Estate, featuring trail races across the Wiltshire Downs in spring. Participants can choose from a marathon, a 20-miler, and a half marathon, with 7-mile and 10-mile routes also available during the same weekend. This event is a small, family-friendly gathering, attracting a few hundred runners for each of the three main distances, unlike large city races. The setting provides a distinctive atmosphere; Larmer Tree Gardens is an elegant country estate, and the organizers humorously refer to using the Rushmore Estate’s “backyard” for the race routes. The courses consist of hilly trail routes, and the terrain can become muddy based on weather conditions, making it more of a countryside run than a quick road race. The shorter 7-mile and 10-mile races are suitable for beginners and include dog-friendly options, while the half marathon and 20-miler serve as good early-season training for runners preparing for a marathon. The marathon covers the full 26.2 miles, and all finishers in the main races are awarded peacock-shaped medals, each distance featuring a unique design. The event spans Saturday and Sunday, with the marathon, 20-miler, and 7-mile race on Saturday, and the half marathon, 10-mile race, and a dog-friendly 10-mile race on Sunday.

Brighton Marathon & 10K

Brighton Marathon Weekend takes runners through Brighton and Hove each April, featuring a marathon, 10K, and Mile race. The marathon, the primary event, is a road race beginning at Preston Park. It proceeds through central Brighton, heads east towards Rottingdean, curves west around Hove, and concludes on Madeira Drive, close to Brighton Pier. The race was established by former international athlete Tim Hutchings and local athlete Tom Naylor, and is now managed by London Marathon Events. The event attracted thousands from its inception, with 12,000 entries available for the first edition and 7,589 participants on race day. It rapidly became one of the UK's larger marathons outside London, reporting over 8,000 runners and approximately 120,000 spectators during its second year. Charity participation is significant, with over two hundred charities represented and charity places increasing from 3,000 to 5,000. The race also features a competitive elite field, holding marathon records of 2:09:25 for men and 2:28:50 for women. The men's elite record was broken in four consecutive editions during its initial growth phase.

The Maverick Brighton Trail Marathon 2027

Not the London Marathon Run Again

The Not the London Marathon Run Again is a small Phoenix Running event in Walton on Thames, designed for runners seeking a marathon-style day without the trip into London. It begins at 08:30 on a flat off-road trail alongside the River Thames. The race offers chip timing, a seven-hour cut-off, and no on-the-day entries. With a limit of 150 runners, it resembles a low-key club challenge more than a large city event. The course consists of a 3.28-mile circuit along the riverside towpath; eight laps complete the marathon distance. As the event operates on a timed basis, participants can stop after any lap or continue for as many as they wish within the seven-hour window. This format accommodates those aiming for distances from a short trail run to a full marathon. The course has a total elevation gain of approximately 100 metres. Headphones are permitted, and race numbers are distributed on race morning. The event returns after a significant break since its last running, and local accommodation in Walton on Thames can be limited around race weekend.

About Marathon races in Portsmouth

Portsmouth Coastal Training Notes

Portsmouth hosts 27 Marathon races in 2026 within 80 km of the city centre — upcoming dates, recurring series, and other races nearby, all in one place.

Locals keep running simple here, with Southsea Seafront starting from South Parade Pier and the Portsmouth Coastal Pathway running from Eastney to Portchester. Old Portsmouth to Gunwharf Quays gives you a neat city-centre spin from near the Square Tower. Milton Common Run gives you 9 miles with some grassy terrain when Z2 needs a softer edge. Hilsea Lines keeps runners on paths along the northern shore. Baffins Fit Club meets Monday evenings in Baffins and leans social. The Racers hit Tuesday speed work and Thursday 7-9 mile runs. The Great South Run is the anchor event everyone knows.

Portsmouth North End Cycling Club is the main wheel to follow, with Saturday traffic-free rides at 09:00, Sunday rides at 09:00, and Monday traffic-free rides at 19:45. Locals ride and race from Portsmouth into Havant Borough. Shipwright's Way takes riders from Hayling Island to QECP and on to Bentley when base miles need a bigger day. Portsdown Hill gives the nearest proper lift off the island. Harvesting Lane on Butser and Stock's Lane both ride more like gravel climbs. Deviation Duathlon Fareham and Soggy Bottom Triathlon 2025 Reverse give multisport legs a target.

Spring and summer are the best months, because Portsmouth gets more sunshine than most of the British Isles and July can touch 25°C. July usually gives riders and runners a 21°C average maximum and a 13°C average minimum, so early Z2 and evening intervals both work well. Southsea can still mean running into a headwind, so locals keep a layer handy. Autumn has its own personality, with September highs around 19°C and October highs around 15°C. Winter stays mild, with January averaging 8°C by day and 2°C at night, while light frost and rare snow change grip more than ambition.
