NORTHWEST FORSYTH — Races seem to take place nearly every weekend in the fall, but in how many 5Ks and 10Ks are runners asked to dodge ditches, leap over logs, cross creeks, climb hills, trudge along trails and meddle through mud?

The Frogtown Trail Challenge is set for Saturday as runners on a 4-mile or 10-mile course will be faced with natural obstacles to hone their inner Tarzan. Proceeds from the annual event benefit the Cumming Civitan Club Inc.

Participation is limited to 1,000 runners, so there will be no race-day registration unless the event doesn’t sell out. As of Tuesday, there were still spots available.

Entry fees are $55 for the 4-mile race and $60 for the 10-mile course.

Race day check-in is at 6:45 a.m., with the races beginning at 8 and 8:15 a.m. at Old Federal and Nicholson roads in northwest Forsyth.

Testimonials from the event website describe the race as a “flagged route through the wilderness,” involving “running in a creek for a mile? Yep, you’ll do it. Using a rope to climb hills? You’ll do that, too. Scaling a rope wall? Uh huh.”

Awards will be given to the top three chip times in overall male, female, masters and age categories.

A premium “super-soft” short sleeved T-shirt is available for every participant.

Simply running the obstacle course is not the only part of this event.

There are limited primitive camping sites available for $5 each, so participants can arrive the night before and hang out by a bonfire with S’mores.

Bagels and hot coffee will be provided starting at 5:30 a.m. Saturday. To register, visit frogtowntrailchallenge.com.
