Kiwi teenager Sam Ruthe has smashed the U18 world record for the mile and put the athletics world on notice with a phenomenal run at an indoor meet in Boston. Ruthe's time is also the 11th quickest run indoors by any athlete, although he is still 3.70sec outside the extraordinary world record posted a year ago by Norway's Jakob Ingebrigtsen. Sam Ruthe breaks the New Zealand indoor mile record in Boston. Ruthe said it was his first race on an indoor track, as New Zealand didn't have them. The Boston race is the first of four of the mile races Ruthe plans to contest this month, before returning to New Zealand for the national championships in early March.
