This isn’t the first time we’ve heard of Diver. The 41-year-old ran a blazing 2:25 marathon in October of 2018. Diver doesn’t only race on the roads, she’s tackled distances from the 1,500m through the marathon with impressive personal bests in the 5,000m and 10K especially, in 15:23 and 31:50. She also represented Australia at the 2018 IAAF World Half-Marathon Championships. 


Rachel Cliff finished fifth at the half-marathon in Japan in 1:10:28, just 20 seconds off her own Canadian record of 1:10:08. Cliff set the record at the 2018 Houston half-marathon, breaking Lanni Marchant’s old mark of 1:10:47.
