Finishers on both distances receive a medal.\u003C\u002Fp>\u003Cp>A runnable trail has its own demands: with no climbs to break the rhythm, it is tempting to run continuously and finish out of energy. On the 50 km, plan deliberate walking breaks and a regular fuelling strategy, taking something every thirty to forty minutes. The 25 km is a good stepping stone for half marathon road runners trying off-road running for the first time: the distance remains manageable and the non-technical terrain limits muscle damage. Versatile shoes will do the job most of the time.\u003C\u002Fp>","en",[25,23],"fr",[],[],[25,23],{"lat":30,"lng":31},52.2013318,-0.6104949,{"year":33,"number":8,"firstYear":8},2027,[],[36,39],{"name":37,"distanceFormatted":8,"distanceMeters":38,"discipline":8,"elevationGain":8,"itraPoints":8,"date":9,"time":8,"lastEditionFinisherCount":8},"Trail  50 km",50000,{"name":40,"distanceFormatted":8,"distanceMeters":41,"discipline":8,"elevationGain":8,"itraPoints":8,"date":9,"time":8,"lastEditionFinisherCount":8},"Trail  25 km",25000,[43,54,63,69,77,86],{"permalink":44,"name":45,"startDate":46,"city":47,"distances":48,"distanceKm":52,"ficheLocales":53},"dirt-run-irchester-country-park-round-1","Dirt Run Irchester Country Park - Round 1","2027-01-24","Little Irchester",[49,50,51],"15 km","10 km","5 km",10,[23],{"permalink":55,"name":56,"startDate":57,"city":58,"distances":59,"distanceKm":61,"ficheLocales":62},"atw-bedford-10k-half-marathon","ATW Bedford 10k & Half Marathon","2026-11-01","Russell Park, Bedford, Bedfordshire, MK40 3RH",[60,50],"21.1 km",13,[23],{"permalink":64,"name":65,"startDate":66,"city":58,"distances":67,"distanceKm":61,"ficheLocales":68},"atw-bedford-half-marathon-10k","ATW Bedford Half Marathon & 10k","2027-02-21",[60,50],[23],{"permalink":70,"name":71,"startDate":46,"city":72,"distances":73,"distanceKm":61,"ficheLocales":76},"atw-bedford-5-10","ATW Bedford 5 & 10","Bedford",[74,75],"10 mi","5 mi",[23],{"permalink":78,"name":79,"startDate":80,"city":81,"distances":82,"distanceKm":84,"ficheLocales":85},"salcey-forest-christmas-10k-5k-junior-fun-run","Salcey Forest Christmas 10k, 5k & Junior Fun Run!","2026-12-13","Hartwell",[83,51,50],"1.2 km",17,[23],{"permalink":87,"name":88,"startDate":66,"city":89,"distances":90,"distanceKm":91,"ficheLocales":92},"milton-keynes-5k-10k-and-half-marathon-winter-warmer-run","Milton Keynes 5K, 10K and Half Marathon Winter Warmer Run","Milton Keynes",[60,50,51],18,[23]]
