Aleksandar Jovanovic, a developer in Dortmund, sold space on his shirt for his first half marathon on 3 October 2026 through a ranked board instead of fixed spots. Bids started at 1 euro, the top bidder took the front and the next ten went on the back. When bidding closed on 20 September, seven sponsors had paid 265 euros in total, and he later posted a finish of about 2 hours 36 minutes.

Lessons

A ranked board lets anyone join for a euro, but the lowest places can bring in almost nothing.
Most of the bidding happened in the first two days, so early promotion counted for the most.
Rules on minimum raises and late bid extensions keep a leaderboard auction fair at the close.
