Trail running and ultra running is growing fast. As races start to sell out across the country, entry fee's for these races seem to go up almost as fast as we have seen the last couple of years in the road running scene. Some bigger ultra trail runs are now owned and operated by bigger for profit corporations and fee's for these races are now hundreds of dollars. Running some of these big name destination races might be cool, but it is something most of us can only afford once or twice a year. Many trail-runner do enjoy racing often throughout the year. So where can you race the rest of the year, preferable locally and for little money? The Naked Prussian is a great option to run/race locally for a very low entry fee. If you sign up early enough your fee will be less the $1 per mile for the ultra and less the $1 per k for the marathon. This is only possible because we chose a location that does not slap us with big permit fees, we don't give you expensive swag ( hence the Naked Prussian) because most of you don't need another race shirt or a flashy 3 pound medal (we will give a little finisher memento)and we are not hiring some aging rockband to entertain you along the course .

The Naked Prussian takes place on the trails around Blue Marsh Lake. These trails are not very rocky or difficult but are true single track trails that require some attention. These trails are great for beginners and the speedy runners alike. The rolling elevation of the trails will keep everybody occupied. The course is not flat or super easy but is doable for most with proper training. Join us next spring to start the new trail running season.

Along the trails of Blue Marsh Lake. One giant 25 mile loop around the lake (26.2 add on 1.2 Mile miniloop at the beginning). 50 Mile runners do it twice ( access to your dropbag at mile 25)

90% of the course is single track trail, the rest features some gravel roads and an old abandoned road section.
No road crossing( exept within the park). The trails are not considered difficult by trail running standards, are very runnable but there will be the occasional rock or root. However this time a year the trails might either be be a bit muddy which will increase difficulty quite a bit.
