2018 Shaw Sundown Showdown - September 29th

Event Information

20K Gravel Bike Race By Day & 10K Trail Run By Night 

Gravel bike race by day and trail run by night at the stunning Shaw Nature Reserve! The only time you will ever get to ride gravel, or run at night in Shaw Nature Reserve! You can participate in one race OR you can participate in both! It is up to you!

Who is the fastest gravel rider in the MidWest? The 20K Gravel bike "sprint" race is perfect for beginners and those who want to test their speed and agility through the 2,400 acres private nature reserve located in Gray Summit, Missouri, that is operated as a division of the Missouri Botanical Garden. This will be the first time a cycling race has been allowed in the park! 

The night trail run course is a 10k loop that meanders through the beautiful prairie and woodland habitats. You will run on the gravel loop road and several of the 'behind the scenes' roads used by staff. There is a little something for every runner on this course in one of the most beautiful locales in eastern Missouri. This is the first night run ever at the Shaw Nature Reserve!

Food and drink will be available post-race for all participants.
