    Leadville MTB Stage Race

    Three days, ~103 miles and a shot at an LT100 MTB qualifier coin — the full Race Across the Sky course, split into stages.

    Build Your Personalized Race Fueling Plan — $19

    Overview

    The Life Time Leadville MTB Stage Race splits the iconic 100-mile LT100 MTB course into three consecutive days — Stage 1 out to Twin Lakes (40 mi), Stage 2 up and down Columbine Mine (22 mi), and Stage 3 back into Leadville (41 mi). A sub-11-hour cumulative time earns official finisher status, and finishers are entered into the LT100 MTB qualifier coin drawing. It's Leadville's altitude, terrain and weather — with the added challenge of executing back-to-back fueling and recovery.

    Why Leadville Stage Race is challenging

    • Back-to-back altitude days

      All three stages live above 9,200 ft with a summit at 12,497 ft. VO₂max is suppressed 12–16 % and gastric emptying slows — and fatigue and dehydration compound day over day.

    • Stage 2: Columbine in 22 miles

      The shortest stage is the hardest: ~11 miles up to Columbine Mine and 11 miles back down. Above tree line the effort is at or above threshold with real hypoxia — under-fueling here poisons Stage 3.

    • Recovery window between stages

      You have ~18 hours between stage finishes. Post-stage carbs, protein and fluid replacement decide how your legs feel at the next 9:00 AM gun, not how hard you rode.

    • Weather swings

      Starts near freezing (35–45 °F / 36–45 °F) with midday highs of 65–75 °F. Afternoon thunderstorms, hail and cold rain are realistic on any of the three days, especially on Columbine and Powerline.

    • Cumulative sub-11 h cutoff

      Official finisher status and the LT100 qualifier coin drawing require sub-11 h total. Any single blow-up stage — GI failure, bonk, mechanical, hypothermia — ends the buckle chase.

    • Logistics and travel fatigue

      Stage 1 finishes at Twin Lakes Dam, Stage 3 starts there. Shuttles, bike storage, drop bags and crew handoffs at 10,000 ft add mental load on top of racing.

    Fueling challenges & strategy

    General, evidence-based guidance. Numbers should always be personalized to sweat rate, body mass, fitness and weather.

    Carbohydrate strategy

    Target 60–90 g/hr of mixed glucose:fructose (roughly 1:0.8) on all three stages. Trained guts can push 100–120 g/hr on Stages 1 and 3 (~4–5 h efforts); most riders stay at 70–90 g/hr on Stage 2 because Columbine's intensity suppresses gastric emptying.

    Hydration

    17–34 fl oz/hr baseline, adjusted for the day's temperature and your sweat rate. Dry Rocky Mountain air roughly doubles insensible respiratory losses vs sea level — you will finish dehydrated if you drink to thirst alone.

    Sodium

    400–1000 mg sodium per liter of fluid, tuned to sweat sodium concentration. Salty sweaters compound day over day: what you don't replace on Friday shows up as cramps on Sunday's Powerline climb.

    Caffeine

    3–6 mg/kg body weight per stage, split — e.g. one dose 30–45 min pre-start, second at the last aid before the key climb (Columbine on Stage 2, Powerline on Stage 3). Keep total daily intake under ~6 mg/kg to protect sleep between stages.

    Aid station strategy

    Stage 1: Carter Summit (mi 10) top-off, Outward Bound (mi 24) full reset. Stage 2: Columbine Summit (mi 11) — grab, don't linger. Stage 3: Outward Bound (mi 15.4) full reset, Carter Summit (mi 29.6) last-chance calories before the descent home.

    Pre-stage breakfast

    1–4 g/kg CHO 2–4 hours before each 9:00 AM start, from foods you have rehearsed — oatmeal with banana and honey, white rice with jam, a bagel with jam. Low fiber, low fat, no experiments across the weekend.

    Between-stage recovery (the real edge)

    Within 60 min of each finish: 1.0–1.2 g/kg CHO + 0.3–0.4 g/kg protein and 150 % of estimated fluid loss with sodium. Add a real meal within 2 hours (rice + protein + vegetables). Elevate legs, get 8+ hours of sleep, keep dinner low-fiber before Stage 3.

    Execution by the clock

    Set a 15-minute interval alarm on the head unit each day and treat carbs, fluid and sodium as an appointment. Perceived effort at 10,000 ft lies — the clock does not.

    Carbohydrate loading for Leadville Stage Race

    A structured 48–72 hour carbohydrate-loading protocol tuned for a long day at altitude. Rehearse it before a training block, not for the first time on race week.

    Structure across the weekend

    Full 48 h load into Stage 1, then partial daily top-ups. Aim for 8–10 g/kg CHO on Thu + Fri pre-Stage 1; 6–8 g/kg on Sat pre-Stage 2; 7–9 g/kg on Sun morning pre-Stage 3.

    Low fiber, low fat

    White rice, pasta, bagels, potatoes, jam, honey, sports drink. Avoid whole grains, legumes and heavy sauces for 48–72 h into Stage 1.

    Hydration alongside

    Each additional gram of stored glycogen carries ~3 g of water. Increased urination in the 48 h before Stage 1 is normal.

    Between-stage top-up

    In the 60 min post-finish window: 1.0–1.2 g/kg CHO immediately. Dinner: 2–3 g/kg CHO. Bedtime snack: 30–50 g CHO if you had a big fluid deficit.

    Race-morning breakfast

    1–4 g/kg CHO 2–4 h before each 9:00 AM start. Repeat the exact same meal all three days to isolate variables.

    Sub-9 & sub-12 split targets

    Aid-station splits for the two headline finish goals at Leadville Stage Race: the Big Buckle (sub-9) and the Silver Buckle (sub-12). Use as planning anchors, not as commitments — weather, altitude adaptation and pack dynamics all shift real splits.

    Stage 2 finish (Twin Lakes)2:002:35

    Stage 3 finish (Rodeo Grounds)3:404:15
    Cumulative total≈ 9:00≈ 10:59

    Pacing strategy

    • Stage 1 first 60 min

      Sit in the front third but cap HR at Zone 2 upper. Ambition here costs Sunday, not Friday.

    • Stage 1 climbs

      St. Kevin's and Sugarloaf: threshold cap. Descend fast and clean into Twin Lakes.

    • Stage 2 Columbine climb

      Zone 3 lower slopes → threshold cap above 11,000 ft. Never redline above tree line — it will end your weekend.

    • Stage 2 Columbine descent

      Feed and drink on the fast upper section. Focus and hands on the rough lower section.

    • Stage 3 Powerline

      Fuel and caffeine at Outward Bound, then hike-a-bike the steeps rather than blowing up. Cap HR at threshold.

    • Stage 3 run home

      The finish is faster than it feels. Keep drinking and fueling to the final 30 min — riders coast in dehydrated and cost themselves 5+ min.

    Altitude sickness (AMS) — prevention & red flags

    Evidence-based prevention and safety guidance for Leadville Stage Race. Not medical advice — discuss altitude medications and pre-existing conditions with a qualified physician.

    • Acclimatization windows

      Best options: arrive 5–7+ days early, or 14–21+ days for meaningful hematological adaptation. Worst option: arrive 2–4 days before Stage 1 — this is when AMS peaks. If limited to a short trip, arrive within 24 hours of Stage 1.

    • AMS symptoms to know

      Headache, nausea, poor sleep, loss of appetite, dizziness. Mild AMS is common above 8,200 ft; typically resolves in 24–48 h with hydration, rest and NSAIDs (informational — discuss with your physician).

    • Red flags — pull out

      Confusion, ataxia (unable to walk heel-to-toe), extreme shortness of breath at rest, coughing frothy sputum. These suggest HACE/HAPE — descend immediately and seek medical care.

    • Hydration and sleep

      Increase fluid by ~34 fl oz/day above sea-level baseline. Sleep quality often drops the first 2–3 nights — expect it and avoid alcohol until after Stage 3.

    • Iron status

      Ferritin under 40 ng/mL blunts altitude performance and recovery. Test 8–12 weeks out; supplement with your physician if needed.

    Equipment & bike setup

    • Bike

      XC hardtail or 100 mm full-suspension. Reliability > weight — this bike races three days back to back.

    • Tires

      2.25–2.4 in tubeless with reinforced casing (EXO+, Grid, Endurance).

    • Pressure

      20–26 psi front / 22–28 psi rear, tuned to rider weight. Recheck every morning — cold nights shift PSI.

    • Gearing

      1x12 with a 30–32 T ring and 10–52 T cassette lets you spin at 60–70 rpm on Columbine at altitude.

    • Hydration setup

      One frame bottle + 51–68 fl oz pack with concentrated carb mix — 90–120 g CHO on board between aid stations.

    • Clothing

      Arm warmers + vest + full-finger gloves for the cold start; jersey + bibs base; rain shell in the pack for Columbine and Powerline.

    • Spares

      2× CO₂ + inflator, plugs, spare tube, quick link, spare hanger, chain lube for morning re-lube each day.

    • Cockpit

      GPS head unit with 15-min fuel alarm; heart rate strap; power meter if you race by power.

    Training for Leadville Stage Race

    • Volume ramp

      Peak training weeks include 12–16 h of riding with two rides over 4 h, ideally back to back on weekends to simulate stage-race fatigue.

    • Back-to-back long rides

      The single most specific training block: 4–5 h Saturday + 3–4 h Sunday for 3–5 weekends in the 8 weeks before race day.

    • Altitude or heat prep

      Live-high or altitude tent (2–3 weeks), or heat acclimation (10–14 days of 60 min in 95 °F / 95 °F) if altitude is not accessible.

    • Threshold and VO₂

      2×20 min at threshold and 5×5 min at VO₂max weekly through the build phase — Columbine punishes riders with no top end.

    • Nutrition rehearsal

      Every long ride uses race-day products, timing and volumes. Train the gut to 90–120 g CHO/h over 6–8 weeks.

    • Descending and technical skills

      Powerline and Columbine descent decide 10+ min for many riders. Practice loose, chundery descents at speed.

    • Iron and ferritin

      Altitude performance is bounded by iron status. Test ferritin 8–12 weeks out; supplement if under 40 ng/mL (evidence-based range for endurance athletes).

    • Taper

      10-day taper: reduce volume 40–50 %, keep intensity, add sleep. Arrive rested — the stage race compounds any pre-existing fatigue.

    Race-day morning timeline

    T-4 hWake, coffee, breakfast 1–2 g/kg CHO (oatmeal + banana + honey, or bagel + jam). 17 fl oz fluid with sodium.
    T-2 hSecond small feed 30–50 g CHO (rice cake or bagel). Chamois, sunscreen, layers on.

    Getting there, lodging & logistics

    Airports, lodging, packet pickup, parking and crew access for the Leadville Stage Race.

    • Airport and drive

      Fly into Denver (DEN) — ~2 h drive to Leadville. Colorado Springs (COS) is ~2.5 h. Rent a mid-size SUV or wagon for bike + gear + crew.

    • Lodging

      Book Leadville, Twin Lakes or Copper Mountain 6–9 months out — the town fills for Leadville Race Series weekends. VRBO / Airbnb dominate. Camping options at Turquoise Lake and Twin Lakes.

    • Packet pickup

      Thursday 5:00–8:00 PM at LRS Retail (316 Harrison Ave) is strongly encouraged. Friday morning 7:00–8:30 AM at Lake County Rodeo Grounds is available but crowded. Photo ID required. Packets are not mailed.

    • Parking

      Lake County Rodeo Grounds (231 McWethy Dr) is the primary hub. Twin Lakes Dam / County Road 25 is the Stage 1 finish and Stage 3 start. Carpool for Stage 2 — no shuttle service.

    • Shuttles

      Stage 1: 12:00–2:00 PM back to Rodeo Grounds. Stage 3: 7:00–8:30 AM out to Twin Lakes Dam. Reserved during registration; $15/day or $25/two days if purchased at packet pickup (subject to availability). No bikes on shuttles — overnight bike storage provided at Twin Lakes.

    • Cell coverage

      Spotty on course — SMS timing updates lag in backcountry sections. Download offline maps for crew and family tracking.

    What most riders get wrong

    • 01

      Racing Stage 1 like a one-day event

      40 miles feels short. Riders who bury themselves chasing time on Day 1 pay for it on Columbine and lose 20–40 min on Sunday.

    • 02

      Skipping structured recovery

      Beer and burgers at the post-stage dinner are great — after you have already hit CHO, protein and fluid targets. Reverse the order and Stage 3 collapses.

    • 03

      Under-eating on Stage 2 because 'it's only 22 miles'

      It is 2.5–4 hours mostly at or above threshold above 11,000 ft. Fuel it like a 4-hour ride, not a training loop.

    • 04

      New products or gear on race day

      Three stages amplify GI risk. Everything — bottles, mix, gels, chamois, shoes, pack — must be identical to what you rehearsed on long altitude rides.

    • 05

      Wrong tire pressure across stages

      The course rewards fast rolling but punishes thin sidewalls on the descents. 2.25–2.4 in tubeless with reinforced casing, pressure re-checked every morning.

    • 06

      Ignoring the cold start

      35–45 °F at 9:00 AM with a rapid warm-up. Under-layering leads to shivering and suppressed appetite; over-layering leads to overheating and early dehydration. Arm warmers + vest + gloves is the sweet spot.

    • 07

      No crew brief

      Crew and shuttle logistics differ every day (Twin Lakes finish Fri, Twin Lakes start Sun via shuttle). Print a one-pager with times, locations and drop-bag contents per stage.

    • 08

      No altitude acclimatization plan

      Fly in the day before and Columbine will end your weekend. Arrive 5–7+ days early, or arrive the night before and accept the performance cost.

    Race history & culture

    • Born from the LT100 MTB

      The Stage Race splits Leadville's iconic 100-mile course into three days, opening the Race Across the Sky experience to riders who want the full course without a single 12-hour effort.

    • The qualifier coin

      Official sub-11 h finishers enter the LT100 MTB coin drawing at Sunday's awards ceremony — one of the few non-lottery paths into the LT100 MTB.

    • Life Time and Kenetik era

      The event is presented by Kenetik under Life Time's Leadville Race Series umbrella, alongside the LT100 MTB, LT100 Run, Silver Rush 50 and Leadville Trail Marathon.

    Why generic fueling plans don't work for Leadville Stage Race

    Two riders on the same start line can need very different fueling. FTP, target finish time, body mass, sweat rate, temperature, altitude adaptation, nutrition products and race goals all change the answer. A generic 60 g/hr recommendation is a starting point, not a plan.
