That's a pace of about 5.4 MPH--a fairly comfortable jogging speed if you have two legs. But Larry Chloupek finished this half marathon while using crutches. He performed this feat at the Rock 'n' Roll Arizona marathon back in January. He recently received confirmation from Guinness World Records that he holds the title of the fastest half marathon completed on crutches.
Hey, it's simple math! I took algebra!!! :P
