There was recently some controversy at the Biotropica Backyard Ultra where both the men's and women's world bests were broken. After the event concluded, it was revealed that some violations occurred, causing all results from the event to be disqualified, including the top performances. Mark Dowdle joined me to discuss what happened, along with other related topics around rules in the sport of ultra marathon.
