Indoor Insanity Is a Fundraiser to Prevent Lung Cancer in Maine

Exposure to radon causes lung cancer: 

  • Radon is the second leading cause of lung cancer nation-wide, and the number one cause of lung cancer in non-smokers.
  • High levels of radon gas move up through Maine soil and water, where it can get trapped inside buildings.
  • 1/3 of the homes in Maine (2/3 in Cumberland County!) have radon above the EPA recommended action levels.

Learn more about radon.

The money that YOU raise through your Indoor Insanity registration fees and additional donations will be used to fix radon problems in low-income Maine households.  The Maine Indoor Air Quality Council works with established non-profit organizations here in Maine to identify these households, as well as facilitates the work via registered Maine radon mitigators to install the systems. With your help, we hope to make the indoor air in 1-5 homes in 2023 a whole lot safer to breathe!  See sample media coverage (from our 2015 mitigation):

You can be a cancer-preventing superhero. Please consider making an extra donation when you register for Indoor Insanity–or even better–set up a fundraising page so that your family, friends, neighbors, and colleagues can join you in preventing lung cancer right here in Maine.  Making a donation is easy and can be done as part of the check-out process*.

(Links to donation and fundraising page set up tutorials are available HERE.)

How Indoor Insanity Works

To minimize injury and “traffic jams”, runners pick their preferred heat based on their general running speed.

  • Heat # 1 – for the fastest runners (15-20 minute 5k)  Field will be limited to 30 runners.
  • Heat # 2 – for the intermediate runners (21-28 minute average 5k)  Field will be limited to 75 runners.
  • Heat # 3 – for runners of any level willing to take on the challenge that only chaos can bring!
  • Walkers are welcome (we will have a dedicated lane for walkers).
  • 1/2 mile Kids Fun Run, too!

Ribbons and bragging rights will be awarded to winners of the various heats. All participants have opportunity to win some terrific door prizes. Special prizes for top male and female runners TBA.

Race Timing and Lap Counting – Get Great Running Data

Indoor Insanity will be professionally chip-timed for accurate individual lap and finish times.  Unlike other 5k races which give you just one finish time, Indoor Insanity 5K participants get 25 pieces of running data – split times for each lap completed.

Lap Counting:  Hand tally counters will be available to help runners keep track of lap numbers.   Please note:  Indoor Insanity participants should not rely on the chip timing company to provide individual lap counts during their heat.  (It’s just not possible – it’s too insane!)  If runners would like that level of support during their race, please bring a spotter.  Spotters will be available at the event on a first come, first served basis.  Cost:  $20 donation to the Indoor Insanity radon mitigation fund.

Race Fees

$30.00 per person.

Thanks to our event sponsors, all proceeds from registration fees and supplemental donations will help support radon mitigations in low income households in Maine.  Please consider making an extra donation at checkout, or even better, set up a fundraising page so that your family, friends, and colleagues can support your efforts to prevent lung cancer.


The first 150 Indoor Insanity participants who register before noon on Friday, January 6, 2023 are guaranteed an event t-shirt.

Cancellation and Refund Policy

Cancellation due to inclement weather:  Should the weather on Sunday, January 12, 2020 create unsafe travel conditions, Indoor Insanity 2020 will be cancelled.  No refunds will be provided.  100% of registration fees and donations collected will be used to fix radon problems in low-income households here in Maine.

Refunds:  No refunds will be given to individual Indoor Insanity participants who need to cancel in advance.  If, however, you wish to transfer your bib number so another individual can take your place, please contact race director Christy Crocker at the offices of the Maine Indoor Air Quality Council:  207-626-8115; christy@maineindoorair.org.






Thank you to the Leukemia & Lymphoma Society for the use of the moniker “Indoor Insanity”.  They, too, host an indoor running event in North Carolina to support cancer prevention, support, and cure.  See www.indoorinsanity.com.
