Frequently Asked Questions

What are the dates for the 17th Annual (2022) MR340?

There are 3 full moon weeks targeted for the race.

Primary date is July 12-15 (safety meeting July 11)

Secondary date is August 9-12 (safety meeting August 8)

Tertiary date is September 13-16 (safety meeting September 12)


Why is the MR340 now part of  Missouri River Relief?  

Rivermiles is still part of the MR340 team.  But River Relief is an organization that puts on river events year round and has the people-power and infrastructure to make it work long into the future.  Rivermiles is just a handful of people who are all getting old!  The race is in better hands long term with Missouri River Relief.

How does the fundraising work?

When you register for the race a $50 fee is required.  There is an additional requirement to raise a minimum of $200 for Missouri River Relief.  A fundraising page will be automatically created for you to share if you wish.  It’s very easy for friends or family to make a tax deductible donation to River Relief towards your goal.  Whatever amount you haven’t raised by April 1st will be charged to your card. If you register after April 1 the full $250 will be required upon registration.

If you exceed the $200 there are prizes available from our sponsors at various levels.

What if the race gets postponed?

It’s possible the race could be postponed due to flooding or other issues of safety.  This has happened 4 times in the previous 15 races.  The 3 dates are hopefully adequate for the race to be held safely.  If there is a year where it is unsafe to race all the available dates, there will be no 340 that year.

If that’s the case your entire entry fee becomes a tax-deductible donation.  A donation receipt will be emailed for the full amount.

How fast does the race sell out? Is there a waiting list?

The race sells out every year.  It’s hard to predict.  The 7am solo start sells out first at around 350 boats.  The 8am start usually fills up slower for the tandem and larger boats.  Yes, we plan to have a waiting list.  Contact scott@rivermiles.com

Are there refunds?

No, there are no refunds.  This is the major fundraising event for Missouri River Relief.  River Relief has employees and many fixed cost obligations that rely totally on fundraising.  Their budget depends on a consistent, reliable fundraising model.  A no refund policy is consistent with most races that support a non-profit organization.
