If you downloaded the Run on Less – Messy Middle dataset prior to November 19, 2025, please note there is an updated file. Download it here.

We’ve released a dataset from Run on Less – Messy Middle that contains information on various performance aspects of the 14 vehicles in the Run.

We will publish a report in January on the mechanics of the Run; we will hold a “potluck” data analysis workshop in Boulder February 17-18; and we will publish a detailed analysis of the findings from the Run by mid-2026. If you would like to present at the data analysis workshop, email rob.graff@nacfe.org to be invited to a virtual informational meeting on December 2 at 2 pm ET.

As you review the data, please share your comments with us on what you find to be key learnings.

Our goal with this Run was to bring clarity to long-haul trucking. And we are wondering how we did. Click here to answer a couple questions for us – we’d really like to hear from you. Final results will be published in NACFE’s December newsletter.
