Four more years

Double Olympic 1500m medallist Nick Willis has already switched focus to Tokyo in a bid to contest a remarkable fifth Olympic Games. Fresh from snaring a bronze medal in the blue riband event in Rio, New Zealand’s top middle distance runner confirmed Tokyo was in his sights in 2020 when he’ll be 37.

"Committing to another 4 year Olympic campaign. Likely 1500m in 2017, 1500/5000 in ’18, then focus on the 5000m for Tokyo," Willis posted on Twitter from his US base, adding he was hanging up the spikes for the rest of the current season.

The 33-year-old Wellington-raised athlete became the oldest male Olympic 1500m medallist in Rio when he finished third to American Matt Centrowitz and defending champion Taoufik Makhloufi from Algeria.
