This April, the Arkansas Delta calls to gravel cyclists, bikepackers, and ultra endurance athletes ready to trade convenience for commitment. Mile Zero Ultra is a free, self-supported gravel odyssey offering 300 and 600 mile route options across one of the most unique landscapes in Arkansas.
Centered in Helena West Helena, the event follows sections of the Crowley’s Ridge Gravel Trail and the Delta Heritage Trail, blending long stretches of fast rolling gravel with small town culture and deep Delta history. For riders looking for an authentic Arkansas gravel event, this one strips the experience down to its essentials.
A Self Supported Gravel Adventure
Mile Zero Ultra is fully self supported. There are no entry fees, no SAG wagons, and no support crews waiting at checkpoints. Participants carry what they need, plan their resupply stops, and manage their own pace from start to finish.
Organizers provide a digital route description and a suggested start time. Everything else is up to the rider or runner. Whether you are using this event as training for a major ultra distance race or as a personal endurance challenge, the goal is simple. Complete the route.
This format makes Mile Zero Ultra one of the most unique gravel cycling events in Arkansas, appealing to those who value independence, grit, and personal responsibility on the bike.
300 and 600 Mile Route Options
Participants can choose between two distances:
Both routes feature approximately 19,000 feet of elevation gain and loss across fast, flowy gravel surfaces. While the Arkansas Delta is often thought of as flat farmland, Crowley’s Ridge adds surprising contour and rhythm to the ride.
Depending on your style, hotel stays or bivy camping, expect to spend four to nine nights on the route. The combination of remote stretches, rural communities, and scenic ridgelines creates a true gravel odyssey through eastern Arkansas.
For those searching for long distance gravel routes in Arkansas, this event showcases the potential of the Crowley’s Ridge Gravel Trail and the growing Delta Heritage Trail network.
The Homecoming in Helena
The journey culminates in historic Helena West Helena, where riders are encouraged to return by 3:00 PM on Saturday, April 11, to be welcomed back during the Mile Zero Delta Outdoor Festival.
After days spent navigating gravel roads and quiet Delta highways, rolling back into a lively downtown celebration provides a powerful contrast. It is less about a traditional finish line and more about returning to a community.
Why the Arkansas Delta Is Ideal for Gravel Cycling
The Arkansas Delta continues to emerge as a destination for gravel cycling and bikepacking. The Delta Heritage Trail offers long, uninterrupted stretches of riding, while Crowley’s Ridge provides elevation, views, and a distinct geological feature that sets the region apart.
Together, they create a challenging and scenic endurance route that highlights a lesser known side of Arkansas outdoor recreation.
Registration and Event Details
There is no entry fee, but participants are asked to register in advance through BikeReg.
Mile Zero Ultra is not a fully supported gravel race. It is a self supported endurance challenge designed for riders and runners who want to test themselves across hundreds of miles of Arkansas gravel.
For those seeking a true gravel adventure in Arkansas, Mile Zero Ultra begins and ends in Helena. Everything in between is up to you.
