The number varies from source to source. According to Speedgoat Karl's Twitter bio, he has 46 victories to his name. Add to that speed records in hikes and endurance challenges like the Red Bull Human Express (setting the record for the Pony Express Trail from Sacramento, CA, to St Joseph, MO, 2064 miles, in 40 days, and doing 105 miles on his last day in 19 hours 21 minutes), and you have one of the most impressive trail portfolios on the planet.
