Grindstone Lake

Mountain reservoir at ~6,900 ft elevation, surrounded by pine forest at the edge of the Lincoln National Forest. Clear, calm water — not a river, not an ocean. No current.

Water temp: historically 63–64°F on this weekend. Cold. Wetsuit almost certainly required.

Bike · 40K

Through town → toward Hondo → back

Roll out of Ruidoso village onto the highway heading east toward the small community of Hondo. Open Sierra Blanca views, mountain-desert terrain. Rolling hills, likely some exposure to wind and sun.

Elevation gain: expect meaningful climbs both directions. This is not a flat course.

Run · 10K

Village + neighborhoods → Midtown finish

Winds through the mountain village and scenic residential neighborhoods. Hilly — Ruidoso has no flat anywhere. Finish line is in the heart of Midtown, the walkable commercial heart of the village.

Expect: shade from pine trees in spots, exposed sun in others. Cool mountain air makes this easier than a Lubbock 10K.

★ The elevation factor

Ruidoso sits at ~6,900 ft. Lubbock is ~3,200 ft. That's a 3,700-foot gain, and it affects performance. Aerobic capacity drops roughly 8–12% at this altitude for un-acclimatized athletes from low elevation. Translation: a pace that feels like Z2 in Lubbock will feel like Z3 in Ruidoso. Your legs won't know the difference; your lungs will.

Strategies that help: arrive 24–48 hours before the race (arriving 3–4 days out puts you in the peak altitude-sickness window, counterintuitively worse than arriving the day before). Hydrate aggressively from Wednesday on. Expect your heart rate to run 5–10 bpm higher than normal at any given pace. Adjust effort by RPE, not pace or HR targets.

Translation for race day: don't chase your Lubbock pace. Race the effort, not the watch.

The Ironman festival weekend in Ruidoso is brand new in 2026 — the 5150 is the Olympic-distance sibling of the inaugural 70.3. You'll be racing the first edition. Pretty cool.
▸ Heart-Rate & Pace Zones · Reference +

Set your zones with the benchmark tests in Week 2 & Week 9. Until then, use RPE (perceived effort, 1–10) as your guide.

Run (% of 5K pace)

Z1Recovery · RPE 2–3 · 75%+
Z2Endurance · RPE 3–4 · 80–85%
Z3Tempo · RPE 5–6 · 90–95%
Z4Threshold · RPE 7–8 · 5K pace
Z5VO2 · RPE 9 · Faster than 5K

Bike (% of FTP)

Z1Recovery · RPE 2 · <55%
Z2Endurance · RPE 3–4 · 56–75%
Z3Tempo · RPE 5–6 · 76–90%

Benchmark tests are marked in Week 2 & Week 9. Complete these first to dial in your real numbers — then every "Z2," "race pace," or "tempo" below becomes actionable. Until tested, RPE is your north star.
▸ Daily Fueling Reference · +

Daily carb targets scale with your current weight (edit at top of page). Detailed protocols for specific long sessions appear on those weeks. Numbers like this are personalized to your weight.

Three principles that matter more than the math:

1. Eat to fuel the next day's training, not yesterday's — protein + carbs within 2 hours of a hard session.
2. Long sessions > 75 minutes need in-session carbs. Shorter sessions just need water.
3. Nothing new on race day — every gel, bottle, and breakfast used in the race must first be tested on a training brick.
PHASE 01 · WEEKS 1–4
Base
Apr 20 — May 17
Aerobic foundation. Consistency over intensity.
PHASE 02 · WEEKS 5–9
Build
May 18 — Jun 21
Intervals, tempo, weekly bricks.
PHASE 03 · WEEKS 10–12
Peak & Taper
Jun 22 — Jul 11
Race-specific, rehearsal, rest, race.
★ STRATEGY ·   Solid, sustainable build. Long sessions reach race distance by Week 8 with modest overshoot. Race day you'll be prepared, not burnt.
