Pikes Peak Ascent

A short history

The Pikes Peak Ascent is one of the oldest and steepest mountain races in North America. The Barr Trail climbs 2,400 vertical metres in 21 kilometres from the town of Manitou Springs to the 14,115 ft (4,302 m) summit of Pikes Peak — the same peak Katharine Lee Bates was looking out from in 1893 when she wrote "America the Beautiful."

The annual Pikes Peak Marathon (run on this route in both directions, ascent + descent) has happened every August since 1956. The Ascent-only race is the half-marathon variant — same climb, finish at the summit, ride down in a vehicle.

It's not a fast race for anybody. Even elite mountain runners take 2:00-2:30 for the Ascent because you simply cannot push above ~3,500 m of altitude the way you would at sea level. Most finishers walk the last 3 km above treeline.

About this GPX

This is full-resolution Barr Trail geometry sourced directly from OpenStreetMap, with elevation enriched from USGS NED 10-metre terrain data via OpenTopoData.

How it was built:

1. Queried OpenStreetMap (Overpass API) for every highway=path way tagged name="Barr Trail" — 23 connected segments / 1,425 nodes.
2. Stitched them into a single ordered chain from the trailhead at the top of Ruxton Avenue (38.856°N, -104.934°W, 2,040 m) to the Pikes Peak summit (38.841°N, -105.042°W, 4,294 m), choosing the direction that minimises distance to the summit at each branch.
3. Prepended ~12 hand-traced road waypoints from the race's Memorial Park start in Manitou Springs, climbing Manitou Ave → Ruxton Ave → Hydro St up to the trailhead — covering the first 2 km that the actual race runs on pavement before hitting dirt.
4. Queried OpenTopoData USGS NED 10m for elevation at every node (the same dataset USGS uses for their official 7.5-minute topographic maps).
5. 3-point smoothed the elevation to absorb the ±1 m noise that NED sometimes shows on steep terrain.

Final stats:

• 1,437 waypoints — every switchback the actual Barr Trail makes is preserved
• Elevation accuracy: ±1 m (USGS NED 10m is the gold standard for US terrain)
• Total distance: 21.02 km (matches certified race length)
• Net climb: +2,488 m gain (1,920 → 4,294 m, with the small descents OSM records preserved)

Treadmill simulation notes

This is a different kind of treadmill workout. You're climbing for the entire run — there's no flat, no descent, no recovery section. The auto-incline simulation will push your treadmill between 5% and 12% for most of the climb, peaking at the steep section above treeline (km 15-18).

Pacing reality:

• Forget your normal pace. A 6 min/km runner on flat ground will be a 9-12 min/km runner on Pikes Peak. That's not weakness; that's gravity and altitude (which the treadmill can't simulate but the gradient can).
• Walking is part of the race. Even Olympic mountain runners walk parts of the upper trail. If your treadmill has high enough incline, you'll be walking too.
• Hydration matters more than pace. The real race finishes at 4,300 m where the air is half as dense. Indoor running burns more fluid than people expect — drink early.

If your treadmill maxes out at 15% incline (most do), the simulation caps the steep sections at 15% and you'll be slightly under-loaded vs the actual climb. To compensate, hold a strong walking pace through km 15-18 instead of jogging — the time-on-feet stays honest.
