Nielson Challenge July

Nielson Challenge July takes place in Colorado Springs, Colorado, on May 1, 2027. A single distance is offered, 3.2 km, or roughly 2 miles, on a course run at altitude in the mountain landscape typical of the region. No start time or elevation gain is listed.

Two miles is a genuinely hard distance to race well: too long to sprint, too short to settle into. Run it as a controlled effort from the gun rather than a fast opening quarter followed by damage limitation. Altitude adds another layer if you are visiting from lower ground, where the same pace simply costs more, so judge the day on placing and effort instead of the clock. Short, sharp repetitions once a week for a month is the most useful preparation.
