Diósjenő BikExpert Specialized mtb és terepfutó Challenge

The start is at Forest Leisure Park, adjacent to the forestry site, making this a woodland-focused event rather than a typical road race. It is part of the Maraton Challenge series, which includes trail running alongside walking tours, MTB touring, and mountain-bike racing, retaining the original "MTB and trail-running Challenge" spirit. Expect a diverse group of participants: runners, riders, walkers, children, families, and pairs competing in longer distances. Men's, women's, and mixed teams in the pairs category are ranked by their second finisher's time. A notable feature is the series raffle held at the final event, offering significant prizes valued in the millions of forints; participation in more rounds increases your chances in the draw.
