This week, we got to talk to David Eliuk about what it took to set the Guinness World Record for Most T-Shirts Worn During a Half-Marathon. David described how he decided on this goal, how he trained, the requirements for the record to be recognized, and the challenges he faced along the way. Running 13.1 miles while wearing 120 shirts is no mean feat, and it was fun to hear about David's background, goals, and challenges.
