There is a single race on the programme: a 21.1 km road half marathon starting at 8:30am. No elevation gain has been published for the course.\u003C\u002Fp>\u003Cp>The race name points to a route linked to the Thames, which suggests a fairly gentle profile that lends itself to even pacing. It is the kind of event where a fast time is a realistic target: two 10 km blocks run at the same speed are worth more than a first third taken out too quickly. For runners tackling their first half, a sensible goal is to finish without walking, settling into the pace of their long training runs. The morning start means arriving early enough for a proper warm-up.\u003C\u002Fp>","en",[26,24],"fr",[],[],[26,24],{"lat":31,"lng":32},51.3875458,-0.431075800000031,{"year":34,"number":8,"firstYear":8},2026,[],[37],{"name":7,"distanceFormatted":8,"distanceMeters":38,"discipline":8,"elevationGain":8,"itraPoints":8,"date":9,"time":8,"lastEditionFinisherCount":8},21097,[40,49,54,63,72,79],{"permalink":41,"name":42,"startDate":43,"city":44,"distances":45,"distanceKm":47,"ficheLocales":48},"kingston-10k","Kingston 10k","2026-11-22","Greater London",[46],"10 km",10,[24],{"permalink":50,"name":51,"startDate":43,"city":44,"distances":52,"distanceKm":47,"ficheLocales":53},"runuk-kingston-half-marathon","RunUK Kingston Half Marathon",[16],[24],{"permalink":55,"name":56,"startDate":57,"city":58,"distances":59,"distanceKm":61,"ficheLocales":62},"the-london-riverside-1-5k-10k-and-half-marathon-morun","The London Riverside 1.5k, 10k and Half Marathon MoRun","2026-11-29","Twickenham",[16,46,60],"1500 m",12,[24],{"permalink":64,"name":65,"startDate":66,"city":67,"distances":68,"distanceKm":61,"ficheLocales":71},"marathon-de-richmond-2026"," Marathon de Richmond","2026-11-14","Richmond",[69,16,70],"42.2 km","8 km",[24],{"permalink":73,"name":74,"startDate":75,"city":76,"distances":77,"distanceKm":61,"ficheLocales":78},"runuk-richmond-half-marathon-autumn","RunUK Richmond Half Marathon Autumn","2026-11-01","Old Deer Park - Richmond Upon Thames TW9 2SF",[16],[24],{"permalink":80,"name":81,"startDate":82,"city":67,"distances":83,"distanceKm":86,"ficheLocales":87},"london-1-5k-5k-10k-and-half-marathon-morun","London 1.5k, 5k,10k and Half Marathon MoRun","2026-11-08",[16,46,84,85],"5 km","1.5 km",14,[24]]
