What precautions is TCM taking to ensure my safety?

We at Twin Cities In Motion have spent much of the past year working with our permitting municipalities and agencies, the State of Minnesota, and medical and crowd science experts to determine how we can best provide an in-person racing experience at the Medtronic Twin Cities Marathon Weekend this October. While all of the details aren’t finalized yet, we remain optimistic that an in-person event will take place and are committed to providing a safe return to large-scale racing in the Twin Cities that follows all relevant guidance and also ignites everyone’s inner athlete.

Here’s what you will see at the Medtronic Twin Cities Marathon Weekend this fall:

  • Reduced field sizes
  • Mask-wearing requirements except for while racing
  • Social distancing requirements
  • Spectators discouraged and spectator access limited in certain areas
  • Reduced touchpoints when possible

Can I make any changes to my registration?

I can no longer make the event. Can I transfer to a friend?

Yes, however you may only transfer the entire series (10K, 5K, and 10M) as a whole. Series registrations may not be parsed out with one distance going to one person and another distance or two going to another person. The deadline to transfer your entire race series is August 26, 2021 at 5 p.m. After that date your series registration is non transferable. Please follow this link to initiate a transfer. There is a $15 transfer fee.

Can I receive a refund or defer my entry to another date?

Refunds are available within 48 hours of registration. This policy is valid until 5 days before the event. To request a refund, email  within 48 hours of when you submitted your registration. If accepted, you will be refunded your race entry fee; online transaction fees are non-refundable. 

What will happen to my registration if the event is cancelled due to COVID-19?

Registration for the 2021 TC Loony Challenge is non-refundable, except if state or local authorities mandate race cancelation due to the Covid-19 Pandemic, in which case TCM will provide a partial refund in the amount of $45, convert all in-person registrants to the virtual event, and mail out all race amenities.

What is included with entry?

The TCM Loony Challenge includes:

  • Individual race entry for each individual event in the series
  • Custom premium Loony Challenge swag item and medal
  • 5K/10K short sleeve Brooks technical shirt and medal (5K and 10K are the same shirt and medal)
  • 10 Mile long sleeve Brooks technical shirt and medal

Race weekend amenities are TBD—check back later this summer for details!
