A Kansas man managed to run a marathon and knit a scarf to break a world record. David Babcock thought it would be a good idea to combine two different hobbies to break a world record. The 41-year-old managed to achieve his goal after knitting a scarf that was twelve-feet long while running the Kansas City Marathon in a time of five hours and 48 minutes. He surpassed the previous record of making a scarf that was six-feet and nine inches.
