London's flattest half marathon

Looking for a tune-up race pre-London, Manchester or Brighton? Kew the Run offers a flat and fast course, presenting a perfect chance to lock in to some marathon-paced miles.

There are also Xempo pace makers to help you judge your pace.

The Kew Gardens Half Marathon course features several iconic landmarks within the Royal Botanic Gardens, Kew. Runners will pass by the Palm House, Temperate House, and the Great Pagoda. The course also includes the Broad Walk, Queen Charlotte’s Cottage, the Kitchen Garden, The Hive, and Giant Redwoods.

Highlights of the gardens

  • The Broad Walk - start

    Just over 300 meters long, the broadwalk offers an adventure for the sense – with fresh fragrances, dazzling flowers beds and feathery grasses in a joyful display that evolves with the seasons.

The Broadwalk
  • Palm House

    Palm House is a remarkable indoor rainforest, home to tropical plants from some of the most threatened environments in the world. Many plants in this collection are endangered in the wild, some even extinct.

Palm House
  • Queen Charlotte's Cottage

    In spring the bluebells take over the beautiful wooded area that includes Queen Charlotte’s Cottage. The cottage was built as a country retreat, used by the Royal family in the late 18th for resting and taking tea during walks in the gardens. Many exotic animals were kept in the paddocks, including cattle, tigers and even kangaroos.

Queen Charlotte's Cottage
  • The Great Pagoda

    Kew’s Pagoda was created in 1762 as a gift for Princess Augusta, the founder of the gardens. The structure has had withstood a lot of adversity in it’s time. During the second world war British bombers used the Pagoda as target practice, repair holes are still visible today.

Pagoda
  • The Temperate House

    Filled with 10,00 individual plants, this vast collection may help us find solutions to some of the world’s most pressing issues, from climate change to loss of biodiversity or food security.

The Temperate House
  • Kitchen Garden

    In Georgian times, the Kitchen Garden supplied members of the royal family living in Kew Palace. Today, the fruit and vegetables from the garden are used in Kew’s restaurant. Also, more unusual and experimental crops are grown in the gardens, as they may become an important source of food for the future as the climate becomes more unpredictable.

Kitchen Garden
  • The Hive

    A visual tribute to Britain honeybees, surrounded by wildflowers, celebrating the environment that real bees need to thrive. The Hive’s mesh frame is constructed from 170,000 aluminium parts and 1,000 LED lights.

The Hive
  • Syon House

    After exiting the gardens and start running down the towpath towards Richmond, on your right-handside over the river you can see Syon House. Syon House, is a beautiful house and home of the Duke of Northumberland for over 400 years. Syon House has a great history, being used a hospital during the First World War and sustaining damage during the Second World War, resulting in the house being opened to the public to cover maintenance costs.

Syon House

After the events, finishers and their families can explore London’s no. 1 visited tourist attraction, Kew Gardens, which holds 50,000 living plants to be found across the UNESCO World Heritage site.

An all round amazing event. How often are you allowed to run around Kew Gardens? The venue is fab, marshals are wonderful - singing, dancing, drumming, acting, hi-fives, shoutouts over the microphone, charity stalls cheering - you name it they do it! Not a single complaint about the route, something for everyone. Stunning stunning stunning. Leanne S

I’ve done this race three times in a row now and love it more each time. Organisation and crowd support is second-to-none, fantastic atmosphere the whole way around and wonderful happy volunteers at the end. It’s not a cheap race but it is good value for money when you consider the top quality Nike T-shirt and fab medal in the goody bag and, the best thing, that you can bring spectators in with you and you can stay as long as you like in Kew Gardens after the race. Shona G

Great flat 10km inside Kew gardens. Well organised and excellent atmosphere on the way round. Highly recommend. Alex D

This is a beautiful (flat) run, in the most unbelievable surroundings. I will definitely be signing up again next year! Georgina S

Kew Gardens is a beautiful setting for a run as the gardens are always stunningly kept. It was lovely to run past the famous greenhouse conservatory. The whole run was on paths within the grounds. Riaz H

A really nice race in an interesting and scenic location. Organisation was good, finishers pack was amazing (loved the Cadburys creme egg), great medal... a very enjoyable morning and a real selling point that you can stay in the gardens after the race. Rebecca C

Free entry to Kew gardens for you and your tribe is included with the entry of racing the race. Will W
