Online registration for the Twin Cities Marathon in Minneapolis will open on Feb. 2, 10 a.m. CST, and this year for their 35th anniversary they’re giving away a very unique prize.

Runners who register before the first price increase on Feb. 10 will be eligible to win the Grand VIP Package, which includes: Two tickets to the finish line VIP tent and a personal porta-potty at the start line reserved exclusively for the winner and their friends.

“We know how important toilet availability is to runners before a race, and we realized this is something we could actually offer a runner,” said Virginia Brophy Achman, the Executive Director of Twin Cities in Motion, on how they came up with the idea. “It’s not difficult to manage one VIP portable restroom, and we thought runners would have fun vying for the prize.”

Indeed, now that popular marathons and half marathons such as Twin Cities are growing in participants, porta-potties at the start line have become a limited supply in high demand with long, and sometimes stressful, wait lines. Last year’s New York City Marathon, the largest marathon in the U.S., had set up 1,748 portable toilets at the race start to cater to its 50,000-plus entrants.
