Bosque Bigfoot FreeAss 50k!
Start time is at 7:00AM.The map will be posted soon
We will have an aid station stocked with common aid station fuel. Tailwind Nutrition and Gu Energy Labs have been awesome enough to send us fuel for our event! 

Bosque Run Shop is running a drive to collect toiletries and non perishable items to donate to Joy Junction so bring anything you would like to donate.
To make this event fun we are also offering the option to do a race shirt/gear swap. Anyone that wants to participate can bring a race shirt they don't wear or want or race gear that has been gently used to put in the swap. Anytime someone finishes their desired distance they will choose an item from the swap! This is a good time to get rid of that race shirt that you have been keeping in the closet collecting dust to someone who would appreciate it! 
If you have any questions/ concerns/ comments please reach out to us through the comments or through our RaceNM inbox.
WE are excited to see all you amazing runners out there taking on the Bosque Bigfoot FreeAss 50k!!!
