Ex2 put on a well run event as usual. I’ve ran in their events for the last 5 years. This park is less than 15 mins from my home and couldn’t miss running it again. The trails were in great condition and the weather was perfect. If you looking for good trail running around the DMV area, look no further than EX2 Adventures.

Once I seen the temps and knowing the course, I switched from the Half-Marathon to the 10K. Needless to say, this was a struggle as hiked all the rolling hills. This was still a fun event as EX2 puts on the most friendly events in the area. I just love the vibe of EX2 events. Hard to explain but one you must experience. Any of their events is a must if you are near the DMV!
