Mammoth March 2026 - 20 MILES

MammothMarch20 – spend a beautiful day hiking and finish 20 miles in 8 hours. Sounds like a piece of cake? You decide!

My start time is 7:45am. It's twenty miles long but it's in November so it should be fiiine.

Some people mentioned they want to do this so here we are. I'd love to hike with you for this event.

The event costs about $100 depending on when you sign up. https://www.mammothmarch.com/tampa-bay-2026

MammothMarch Tampa Bay
We are thrilled to be back at Alafia River State Park with MammothMarch Tampa Bay for our final 2026 hike!
​
After two sold-out editions in a row, we can’t wait for another 20-mile adventure winding through mixed hardwood forests, pine flatwoods, rolling hills and lakes with an abundance of wildlife – all ready for you to conquer on November 14.
​
Unlike other Florida MammothMarches, our Tampa Bay edition looks a little bit different: Standing out from the relatively flat topography of Central Florida, Alafia River State Park features some of the most radical elevation changes in the Sunshine State. Located just 25 miles southeast of Tampa, MammothMarch at Alafia River State Park makes for the picture-perfect hiking get-away.
​
Mastering our challenge, you will be exhausted, but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!​
