The link below for Race Day Timetable will be updated in September 2023 for the race weekend, Oct. 21-22, 2023. It applies only to that weekend.

All race-related events are listed, including the race-day timetable,* the Tussey Teasers and Discovery Training Series. The mOUnTaiNBACK race, and both series, are run on fire roads consisting of more than 82% packed gravel/dirt and less than 18% pavement. There are no trails on the courses. 

*The Race Day Timetable, posted in late September, applies only to the October race. The link above currently holds the timetable for the 2022 race as an example of what to expect this year.

The Tussey Teasers are a FREE series of timed recreational runs in Rothrock State Forest that take place from February through June on parts of the mOUnTaiNBACK course. The Teasers are ideal for anyone ready to discover for the first time - or get back to - some superb running venues. The six Tussey Teaser runs include water provided and some random awards. One, the Beidleheimer Sidewinder 10K & 20K, includes age- and gender-adjusted (WMA style) results to level the playing field. Runners completing Teasers #1-5 (February's Teaser #0 is a bonus) at are eligible for a grand prize. Here is the 2023 Teasers schedule. Click the links for each race to get the flyer and waiver form for each run.


The 2023 Discovery Series covers the course in the counterclockwise (CCW) direction (the course's original direction.)


For runners interested in training on the Tussey mOUnTaiNBACK 50 Mile Relay and Ultramarathon course, or just some beautiful runs on rolling forest roads, this staged series of weekly runs covers the 12 legs of the 50-mile course, one or two at a time. The 8-week schedule is provided below. There are no trails on these runs or on the 50-mile or 50K race course.

Runs are on Saturday mornings, and runners meet at various locations, as noted below. Runs will begin at 8:00 a.m. each week. We love to have people volunteer to shuttle runners from the meeting area to the start of the race but this is something that is typically arranged by the participants that show up that day. Shuttles are NOT provided by the event organizer.

Go here for a flyer on the Discovery Series. You can view a course map here, which includes links to leg descriptions and an elevation profile.
