Train like an Elite. Race like a Pro.

ELITE-15 HYROX athlete James Kelly coaches you through ongoing structured 10-week blocks blending race-specific running, strength endurance, and HYROX conditioning so you show up faster, stronger and ready to PB.

Choose your path. Train with purpose.

Three core programs built for any level, from first-timers to PB hunters to Worlds qualifiers.

JK HYROX Solo

Ongoing 10-week blocks to race day. Running, strength endurance, HYROX conditioning, accessories.

Join Solo

JK HYROX Doubles

Ongoing 10-week blocks tailored for team strategy, higher intensity and power; do sessions with your partner or solo.

Join Doubles

JK Threshold Running Program

Engine-building plan for HYROX and road racing. Develop aerobic volume, threshold strength, and race-specific sessions.

Build My Engine

JK HYROX Solo


A structured ongoing block that takes you from wherever you’re starting to the start line, primed and ready.

Expect quality running, station mastery, and performance under fatigue.

  • You’ll follow a race-focused build that blends running economy, strength endurance, and HYROX conditioning. Each week layers threshold work, compromised running (stations + run), and station skill so you’re not guessing on race day.

  • 6 training days, 1 rest; ~2–2.5 hours/day. On busy days, keep the threshold run and the HYROX conditioning block, then trim accessories first. Quality beats volume.

    • Threshold run: engine builder; anchors intensity.

    • Compromised run: decisions under fatigue.

    • Station mastery: sled tactics, wall-ball cadence, Ski/Row pacing.

    • Contrast strength: endurance-biased strength that supports running.

  • Do the 60-min run test to set threshold; add Ski/Row thresholds in your first conditioning session. Reduce intensity, keep sharpness, lock pacing and transitions.

  • Guided imagery and a 10-day taper program are available

JK HYROX Doubles

  • Same 10-week backbone, tuned for team racing: slightly higher intensity/power, shared sessions you can complete with your partner (or solo if schedules clash).

  • Establish eachothers’s strengths and roles, pre-plan station splits, and develop race day callouts

  • Every workout includes a partner version (timed handoffs, shared reps, shuttle splits) and a solo alternative that simulates the same demand—no momentum lost if you train alone.

  • Guided imagery and a 10-day taper program are available

Same 10-week structure, tuned for doubles: shared sessions, higher intensity and power elements, and tactics that bring the best out of your partnership, whether it’s for fun or a podium push.

12-Week Threshold Running


Build the running capacity that decides your HYROX finish time, and carries to road racing too. Aerobic volume, threshold strength, and race-specific sessions that make splits fall

  • Hybrid athletes and runners who need a bigger engine for HYROX or road racing. Expect smoother pacing, faster thresholds, and better fatigue resistance.

    • Weeks 1–4: Aerobic base + cruise intervals

    • Weeks 5–8: Threshold builds + hill tempos

    • Weeks 9–12: Race-specific sessions + sharpening

  • Threshold intervals, hill tempos (strength economy), progressive long runs (control + fueling). Pair HYROX work on alternate days or after easy/aerobic; keep threshold days clean.

  • Baseline 30–60-min TT, mid-block recheck, final assessment.

    Track threshold pace, HR drift, RPE. If sleep/HR is off, cap at aerobic; consistency > hero days.

  • Guided imagery sessions are available

More threshold.

More skill.

More race IQ

We focus on quality running and station skill, then hard-wire execution under fatigue, so your time drops where it counts.

  • We spend most quality work near threshold to raise the pace you can actually hold on race day—more speed without cooking your legs.

  • Stations flow straight into runs so your body learns to move well under fatigue; cadence, breathing and posture stay steady even after sleds.

  • We drill sled tactics, wall-ball cadence, Ski/Row pace bands and grip strategies—less time lost, fewer no-reps, cleaner transitions.

  • Strength is programmed to support endurance: targeted sets that build muscular endurance and power without stealing from tomorrow’s run.

  • You get pacing bands, decision rules and guided imagery—so you stay calm, execute the plan and finish with control (even/negative splits).

Everything you need to race better–inside one membership.

High-level structure, direct support, and resources that remove the guesswork.

Questions, answered.

Quick answers so you can hit join with confidence.

  • No. We give you simple swaps for sleds, carries, and wall-balls so the intent of the session stays the same. If you’ve got a sled, DBs/sandbags, and a rower/SkiErg, you’re fine. The notes inside each workout tell you exactly how to adapt.

  • Join any time. It’s an ongoing program, so you jump straight into the current week and follow the welcome steps (threshold test, quick setup, community intro). No waiting room—start training this week.

  • Yes. Keep the threshold run and the HYROX conditioning on busy days, and trim accessories first. You’ll still move the needle because the intent of the session stays intact. Consistency beats perfect scheduling.

  • Same backbone, different emphasis. Doubles adds team pacing, planned handoffs, and a bit more pop for those higher-intensity moments. You’ll get partner versions of sessions and solo alternatives so you never miss a beat if your schedules don’t line up.

  • Totally. Train the Doubles structure solo for now—you’ll learn the tactics and handoff timing so you’re ready the moment you lock in a teammate. When you find your partner, you’re already dangerous.

  • Unlimited messaging inside the Fitr app with replies within 24 hours on weekdays, plus a live workshop every week where you can ask anything. We’re active in the WhatsApp community too, so you’re never training in the dark.

  • You’ll be challenged, not crushed. Volume scales to your fitness and schedule, and we show you how to shorten sessions without losing the purpose. Do the threshold test, start where you are, and build—no ego lifting, no junk miles.

  • All programming runs through Fitr (clean, easy app). We host workshops on Zoom and keep the community tight in WhatsApp. You’ll always see a full week ahead inside Fitr.
