Grant is married to Zena and they have 1 adopted child and 2 biological children. Although Grant claims to have always hated running, apparently due to the harsh training he endured during his national service, he has gone on to run in excess of 70 half marathons, 10 marathons and 8 ultra marathons since he started actively running in 2010. Grant is an avid Red Socker and is your typical back-of-the-pack runner; normally finishing just within the cut-off time, taking the opportunity to chat to loads of people on the way and generally having fun. His best races times are 2 hours 3 minutes for a 21.1km, 3 hours 18 minutes for a 32km and 4 hours 31 minutes for a 42.2km. Grant managed to successfully complete the Comrades Marathon on his third attempt in 2016. He hopes to one day break 2 hours for a half marathon.
