The event, held at Hold Out Brewing, was open to anyone who registered. Participants ran on a single Wahoo KICKR RUN, wearing adidas Hyperboost Edge shoes. The relay required a sustained pace of 46 seconds per mile slower than the record. Read more racing coverage.

Guinness has not confirmed if the record was broken. The event organizers did not disclose the number of participants, presence of an adjudicator, or submission of evidence.
