Yep, the Potowatomi (formerly McNaughton) Trail Runs have brought back the 150 mile option in addition to the 50 and 100 mile. There’s also a 30 mile fun run for those looking for a shorter option. The next party is April 13-15, 2012.
Ten mile loop course with most of the hills in Illinois conveniently located in this particular park and a few stream crossings to boot. Word is…. it’s known to get muddy 😉
