2026 Sponsors
The MR340 race has a unique community of sponsors that not only support Missouri River Relief with funding, but find ways to get involved in the race itself and make it a better experience for everyone. We couldn’t do it without all of them. Thank you.
Please contact Petie Holder petie@riverrelief.org to become a sponsor for the 2026 MR340!
