Jo Robinson and Emma Langstaff completed the London Marathon in 4:15:40 while wearing a giant inflatable elephant costume, setting a world record as the fastest pair to complete a marathon in such attire. The runners are members of the Looe Pioneers running club and undertook this challenge to raise money and awareness for type one diabetes; Emma is a doctor who treats patients with the condition, and both of Jo’s daughters live with it. They trained only twice before race day but managed their stride and cadence effectively during the marathon.
