Pour un premier semi, une préparation de dix à douze semaines avec trois sorties hebdomadaires, dont une longue amenée à 1 h 30, constitue une base solide. Le jour J, l'erreur classique reste le départ trop rapide : viser une première moitié légèrement plus lente que l'allure cible laisse de la marge pour accélérer après le dixième kilomètre.\u003C\u002Fp>","fr",[20],[],[],{"lat":25,"lng":26},51.895927,0.89187400000003,{"year":28,"number":9,"firstYear":9},2027,[],[31],{"name":32,"distanceFormatted":9,"distanceMeters":33,"discipline":9,"elevationGain":9,"itraPoints":9,"date":8,"time":9,"lastEditionFinisherCount":9},"Half Marathon",21097,[35,45,52,62,70,76],{"permalink":36,"name":37,"startDate":38,"city":39,"distances":40,"distanceKm":43,"ficheLocales":44},"chelmsford-half-marathon-2027","Chelmsford Half Marathon","2027-03-07","Chelmsford",[16,41,42],"10 km","5 km",34,[],{"permalink":46,"name":47,"startDate":48,"city":39,"distances":49,"distanceKm":43,"ficheLocales":51},"chelmsford-marathon-half-marathon","Chelmsford Marathon & Half Marathon","2026-10-11",[50,16],"42.2 km",[],{"permalink":53,"name":54,"startDate":55,"city":56,"distances":57,"distanceKm":60,"ficheLocales":61},"southend-rudolph-run","Southend Rudolph Run","2026-12-13","Southend-on-Sea",[58,59],"5 mi","1 mi",42,[],{"permalink":63,"name":64,"startDate":65,"city":66,"distances":67,"distanceKm":68,"ficheLocales":69},"atw-remembrance-runs","ATW Remembrance Runs","2026-11-07","Uttlesford",[16,41,42,59],43,[],{"permalink":71,"name":72,"startDate":8,"city":73,"distances":74,"distanceKm":68,"ficheLocales":75},"atw-debden-10k-and-5k","ATW Debden 10K and 5K","Saffron Walden",[41,42],[],{"permalink":77,"name":78,"startDate":79,"city":80,"distances":81,"distanceKm":83,"ficheLocales":84},"st-peters-way-ultra","St Peters Way Ultra","2027-02-28","High Ongar",[82],"69.2 km",49,[]]
