Kew Gardens Half Marathon


The new Kew Gardens Half Marathon will take place on Sunday 10th April, on closed roads inside Royal Botanic Gardens, Kew, before venturing down the Richmond towpath to finish back at Kew Gardens. This is london's flattest half marathon so with good training you'll run a personal best. This brand-new and completely flat richmond half marathon joins the Kew 10K as part of the new 'timeoutdoors' KEW THE RUN series. 

Our 2022 Male and Female Cut Finisher Tee's have been released.


'timeoutdoors' Kew The Run is a weekend that hosts the Kew Gardens 10km on 9th April and the Kew Gardens Half Marathon on 10th April. The 10K will take on a new course running entirely inside a flat Kew Gardens. The Half will start and finish inside Kew whilst taking on an additional flat and scenic route of the Richmond Riverside.

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