The Frozen Heart is the 2019 RRCA Maryland State Ultra Championship event!!!!

This is our 6th annual Frozen Heart event – and we are back as your favorite low-key winter race for trail loving runners.

Runners of all abilities are encouraged to challenge themselves to complete one of the three race events. The 3 loop course provides for 3 event distances – 50K, 34K, & 17K. Or, try the Chesapeake Challenge – read more below!

The course consists of 3 loops around St. Mary’s River Park. Runners have the option of completing one loop (17K), two loops (34K), or three loops for the full 50K distance. Distances are approximate and not officially certified. Due to erosion, plate tectonics, and global warming, the course may not measure exactly 50K. In fact, we may have even measured it with a rubber tape measure….

The trails are singletrack and mostly runnable with some technical sections with tree roots. There are some minor hills, but no significant elevation change. Elevation at the finish is roughly the same as the start. The surface of the trail is mostly packed dirt, but there are a few sandy sections and a few areas of crushed stone. Water crossings have bridges, but weather conditions may provide additional challenges on the trail like snow, water, mud – oh my! The course will be clearly marked with streamers and there will also be signs and markers to keep runners on course. Course marshals are loosely provided (and usually includes a runner going the wrong way…).

Due to a significant portion of single track trail, NO pets and NO strollers.
