Here's a fresh Gravel event that touts itself as a National Championship coming up on June 24th. Starting just outside of Lawrence.
With a World Championship just up the road in Nebraska, this would be the logical preparation.
Information here: Gravel National Championship 2017
PLUS the event is needing some volunteers: "We need a few volunteers for the upcoming USECF Gravel Grinder National Championship in Lawrence, Kansas on June 24, 2017.
All volunteers will receive the same swag package provided to participants which includes an event shirt, custom stainless steel event pint glass, limited addition event poster and other event swag. Volunteers will also receive entry into the post race raffle and our eternal gratitude."
