Designing and Constructing Adaptive MTB Trails

  • Avimor Development 5963 West Avimor Drive Boise, ID, 83714 United States (map)

Cost: $250

Level: Intermediate

Maximum Size: 14 students

Location: Avimor Trail System

Schedule: Monday, April 13 | 8:30 AM–12:30 PM (Field-Based)

Description

This half-day field workshop explores Southwest Idaho’s first purpose-built adaptive mountain bike (A-MTB) trail system located within the Avimor trail network. Spearheaded by the Southwest Idaho Mountain Biking Association (SWIMBA) in partnership with professional builders and the adaptive riding community, these trails were developed to meet adaptive mountain biking standards and broaden trail access for riders of all abilities.

Participants will learn how the team translated a vision for inclusivity into a fully realized trail system, with multiple loops designed for a range of skill levels—accommodating adaptive equipment while still delivering fun, flow, and challenge. With input from adaptive riders and community volunteers, the system balances accessibility with high-quality trail experiences.

Riders from the Challenged Athletes Foundation will be on site to demonstrate adaptive mountain bikes and share firsthand insights, offering a valuable perspective on how design decisions translate to real user experiences.

The workshop begins with a group introduction covering the project’s goals, planning, and partnerships, followed by small-group, on-trail field sessions. Topics include terrain selection, adaptive design considerations, construction techniques, and how rider feedback shaped the final built environment.

Learning Objectives

  1. Identify the goals and community impact of Project Inclusive and the Avimor adaptive trail system.

  2. Describe key design criteria that distinguish adaptive MTB trails from conventional mountain bike trails.

  3. Evaluate terrain and trail layout decisions for adaptive trail suitability.

  4. Explain construction techniques and design adjustments that support adaptive rider access while maintaining quality trail experiences.
