BUDAPEST: Alvaro Martin of Spain captured gold in the 20-kilometre race walk in the opening event of the World Athletics Championships on Saturday. Martin moved into the lead with about 5km remaining to finish in one hour 17 minutes and 32 seconds, the fastest time in the world this season, on the soggy 1km loop course that started and finished at picturesque Heroes’ Square. Sweden’s Perseus Karlstrom, a three-time world bronze medallist, won silver in 1:17:39, while Caio Bonfim of Brazil claimed the bronze (1:17:47) to match his medal from the 2017 worlds in London. The 29-year-old Martin, who was fourth at the Tokyo Olympics and seventh at the worlds last year in Eugene, shaved nearly two minutes off his best time. The 29-year-old clutched a Spanish flag down the home stretch, waving it in victory.
