The Shippey Endurance Runs returns to High Ridge, Missouri on January 16th for a weekend of challenging trail running featuring new distances not seen before in the event's history. Nestled quietly in the rolling wooded hills just outside Greater St. Louis lies the Beaumont Scout Reservation, where runners will experience exclusive access to trails typically off-limits to the public. This year marks the introduction of two new ultra-distance options: a 50K on Sunday and a grueling 10-hour cutoff 25K run on Saturday morning. On race day in High Ridge, Missouri, participants can expect cold mornings typical for January but with potential daytime warmth as St. Louis weather is known to be unpredictable. The rolling hills of the Beaumont Scout Reservation provide varied terrain that includes steep climbs and descents along with pine floors and jeep roads. Runners will encounter a mix of firm trails with slightly soft sections, offering both challenge and beauty in every mile. The Shippey Endurance Runs has been an established part of St. Louis’s ultra-running community for years, attracting runners from across the country who are drawn to its unique trail system and supportive race environment. The event honors Merle Shippey, a respected figure within scouting circles, by running on trails that were once off-limits except during this annual race weekend. With no switchbacks in sight, participants must prepare for technical terrain as well as varying weather conditions.
The course details vary each year based on the direction of travel but always offers runners scenic and challenging routes through the Beaumont Scout Reservation’s trails. The 50K run starts Sunday morning with a firm trail surface that may be slightly soft due to winter conditions, while the new 25K option runs Saturday, offering participants three distinct legs at varying distances. For registration, visit https://ultrasignup.com/register.aspx?did=135549. Fees range from $90 for the 25K up to $315 for the full 100-mile event. Bib pickup is available on Friday evening or Saturday morning at the start location: 6480 Beaumont Reservation Drive in High Ridge, Missouri. Runners must bring their confirmation email and photo ID. The Shippey Endurance Runs takes place from January 16th to 17th near Greater St. Louis in High Ridge, Missouri. This event offers an unparalleled opportunity for trail runners to explore some of the most challenging terrain around while contributing to a tradition steeped in community support and respect for local landmarks.
