Since many of our 10K and Half-Marathon runners are running their first-ever trail race, we have included some road races which are similar in terms of elevation change and difficulty. Still, road runners tackling their first trail run at the Endurance Challenge are advised to visit the course ahead of time, practice running off-road, or run at least one trail race beforehand to have an accurate idea of what’s ahead.
