Holcombe Howler Ultra, Half & 10k

About this event

The Holcombe Howler offers three distinct challenges across the rolling Chiltern Hills near Chiswell Green. The 10k serves as a punchy introduction to trail running with 335m of climbing, while the half marathon doubles down on technical terrain and elevation. The ultra pushes into serious territory with 37 miles and over 2000m of ascent through ancient beechwoods and chalk valleys. Each distance brings runners through the same beautiful landscape, just with varying degrees of commitment. The spring timing means fresh greenery and (hopefully) firm trails, though the Chilterns have a reputation for delivering proper English mud when they feel like it. A solid local event with enough variety to keep things interesting across all three distances.
