Thats ~3.5 km/h. What the fuck?  My mom ran her last marathon when she was 49 in just under 3h45. Now she has condishuns, and I mean cancer, and she doesn't run marathons anymore but even during her chemo she ran ~75km per week and she's an avid cyclist too (cycling through Europe with my father, average of 120 km a day).  So there's literally no excuse for this fat hog if people with real condishuns like Dave Fraser and my mom are faster.
