The Rox-Coach here. Arne Klomp, you earned a solid performance in Stuttgart, but there’s too much clean fuel left in the tank waiting to be burned. We’re going to break this down like a race plan you can execute in your next HYROX to move the needle. Think of this as your firmware update—not flashy, but it makes you faster without you even noticing until you cross the finish line that you’ve moved the needle.

Overall Performance

Athlete: Arne Klomp

Age Group: 30-34 | Nationality: German

Event: HYROX Stuttgart 2025

Overall Rank: 497 (Top 42% of 1166)

Age Group Rank: 127 (Top 43% of 289)

Overall Time: 01:23:59

Total Running Time: 39:44 (-1:08 compared to average)

Best Running Lap: 04:36

What stands out here is a runner-leaning profile with a very solid total running time relative to the field, but with notable gaps in certain workstations and transitions that dragged the overall roxzone (the transition time between segments) up. The pace you set early in Running 1 wasn’t sustainable relative to the average for your finish time, which hints at where your brain and body are sharing the workload—your legs want to go fast, but your transitions and some gym-tech segments are siphoning off momentum. Your Roxzone was 9:00, +2:02 compared to the average, placing you 74th percentile in that zone. Translation: you’re leaving time on the table in transitions and some stations, especially when you’re switching gears from cardio to strength pieces.

Strengths you can lean into: your running demands are clearly a strength area—your total running time is faster than average, and your best lap shows you can hold a relatively fast cadence. Your sandbag work is competent but needs to be more efficient and consistent. Your farmer carries were okay but not driving large penalties; on the other hand, the wall balls, sandbag lunges, and burpee broad jump segments are where you can squeeze meaningful gains with targeted skill work and pacing. Your rower and ski erg segments show room for improvement relative to the field, but they’re not catastrophically weak—this is an area where small technique gains and breathing control will pay off in a big way when you’re fatigued. Keep the mindset: you’re built to run; your job is to carry that run speed more cleanly through the gym stations and transitions.

Key takeaways from the splits:

Your running time across the board is competitive and often faster than the comparison group, which aligns with the Total Running Time advantage. That supports a runner-leaning profile, but your start (Running 1) was a touch fast for the pace you could sustain through the gym segments. This is a classic opening mismatch: you punch off the line and your body pays the transition tax later.
Station work: Ski Erg and Rowing times show you can push more power in the gym pieces, but the current percentile ranks indicate inefficiency or technique gaps that accumulate under fatigue. You’re capable of higher wattage here with cleaner form and better breathing control.
Roxzone needs the biggest improvement. 9:00 is a clear signal that refinements in transitions and station-change efficiency will yield outsized gains. The muscle is there; the timer is the enemy right now in transitions.
Wall Balls, Sandbag Lunges, and Burpee Broad Jump are your three anchors for potential improvement. They’re good enough, but the time you save here compounds across the race when you convert those pauses into tempo work.

Segments to Improve

Based on the data, the worst-performing segments (and their improvement targets) are Wall Balls, Sandbag Lunges, and Burpee Broad Jump. The plan below provides a focused path to convert these weak spots into strengths, with a weighted focus to roxzone reductions and station technique. The percentages indicate the recommended focus during training (not only time spent but intensity and specificity).

Wall Balls — Potential Improvement: 00:51 (Target: 06:58 down to 06:07). Focus during training: 42%

Why it matters: Wall Balls are a velocity-dependence station with a high demand on hip hinge, depth control, and breath timing. A faster wall ball translates directly into faster roxzone transitions and reduced fatigue on the next run segment.
Training strategies:
- Wall Ball technique drills: wall ball progression with tempo 2:0 (two breath cycles per rep), emphasizing hip hinge, controlled drop, and powerful extension at the ball release. Use a metronome at 60–70 bpm for breath control.
- Ball-handling and release drills: practice catching and releasing the ball in a controlled manner with a light ball first, then progression to competition weight. Drill: 6 x 10 reps with 10-sec rest, focus on consistent contact at chest height.
- Sets + reps with fatigue emphasis: 5 sets x 12 reps at 14–16 lb ball (or prescribed weight), 20 sec rest, aim to hold a 1.0–1.2 wall-ball pace (seconds per rep) by the end of block.
- Form corrections: ensure the knee track stays stable, avoid depth collapse, and keep the thoracic spine tall to maintain vertical velocity during the throw.

Sandbag Lunges — Potential Improvement: 00:38 (Target: 05:26 down to 04:48). Focus during training: 31%

Why it matters: Efficient lunges reduce fatigue in the second half and improve symmetry across legs, preventing energy leaks that show up in subsequent running splits.
Training strategies:
- Sandbag carry-and-lunge mechanics: practice with a sandbag held in the front rack position; perform walking lunges with controlled tempo (2 counts down, 2 counts up) and deliberate foot placement to minimize knee drift.
- Loaded lunge intervals: 4 x 12 reps per leg with a sandbag weight that allows strict form; 60–90 sec rest, focusing on a stable torso and controlled core engagement.
- Stride length and tempo work: combine sandbag lunges with short runs (4–6 x 200 m) to train the transition from load to run with minimal deceleration.
- Technique cues: keep the knee in line with the toes, avoid knee valgus, maintain the weight between hips and mid-foot so hips do the driving rather than your back.

Burpees Broad Jump (BBJ) — Potential Improvement: 00:19 (Target: 05:18 down to 04:59). Focus during training: 15%

Why it matters: BBJ is a high-power, high-fatigue station; improvement here yields faster respiration recovery and faster roxzone times for the next run.
Training strategies:
- BBJ technique and spacing drills: practice the burpee with strict archer positions and a consistent path; add a single broad jump forward to build distance with minimal wasted vertical height.
- Power conditioning: 3–4 sets of 8 reps of BBJ with 60 sec rest, focusing on explosive hip extension and a fast, consistent landing pattern.
- Breathing and rhythm: practice nasal breathing through the early reps, then mouth-breathing on the later reps to build fatigue resistance without losing form.

Roxzone (transitions) — Focus in training: 40% of overall plan to reduce transition downtime. Current: 9:00; aim to lower toward baseline by 1:30–2:00 by optimizing station changes and movement economy.

Why it matters: Each second saved in transitions is equivalent to gaining in running volume, especially when the total running time is already strong.
Training strategies:
- Transition drills: 2–3 weekly blocks focused solely on transition economy. Practice moving from Ski Erg to Wall Balls to Sandbag Lunges in a compact sequence, with a stopwatch and strict target times. For example, Ski Erg (30–40 sec), then 20–25 sec transition, then Wall Balls (1:20–1:40).
- Flow state sessions: run a micro-race against a clock with 15-second splits: you know when you start a new station; your goal is to stay within that frame without pausing to “collect yourself.”
- Breathing and posture control: emphasize braced core, neutral spine, and diaphragmatic breathing to reset quickly between stations.

It’s crucial to understand that the “Focus during training” percentages reflect where you’ll gain the most ROI. You already have a strong aerobic base; now you’re building efficiency in the gym pieces and, most importantly, the transitions that chew up time. A small improvement in each of these three reps compounds into major gains over the course of a HYROX event. You’re not chasing a miracle; you’re chasing consistency and technique under fatigue.

Race Strategies

Pace management: In Running 1, set a sustainable turnover that you can hold for the first three running segments without forcing a surge. Consider a conservative start around 4:50–4:55 for Running 1, then plane into a slightly quicker pace as you approach Running 2 and Running 3 if you’ve preserved energy in the stations.
Station pacing: Given the wall balls and sandbag lunges are your current bottlenecks, set a cap for each station (e.g., Wall Balls under 1:10 per set; Sandbag Lunges under 1:40 per leg if you’re using a moderate weight). That lets you stay inside a controlled window and avoid a fatigue-driven breakdown late in the race.
Roxzone optimization: Practice the exact sequence of stations with a stopwatch and a timer signal so you always know when to move. The goal is to minimize wasted seconds per transition and maximize continuous movement through each zone. Build a mental cue system: “hips, hands, eyes” for transitions—hips drive, hands manage the implements, eyes stay forward to avoid wasted micro-delays.
Technical work first, fueling second: Keep nutrition and hydration simple and consistent; avoid any new routine on race day. Practice your pre-run fuel plan and hydration schedule during training that aligns with the running cadence you’ve proven you can sustain.

Conclusion

Arne, you’ve demonstrated a solid runner’s base and good work capacity across HYROX stations. The primary growth areas lie in improving Wall Balls, Sandbag Lunges, and Burpee Broad Jump efficiency, plus a focused push to shrink the roxzone. Your Total running time being faster than average indicates you’re a runner at heart, but HYROX asks for a tighter integration of strength-endurance with running. If you can translate 1–2 seconds of faster wall-ball transitions, 1–2 seconds per rep on BBJs, and 10–20 seconds less roxzone time, you’ll move several ranks in the next event and open room to chase big improvements on your best split times.

Remember: “Stay hard.” Every rep you refine is a step toward holding a higher pace with less fatigue in the final minutes. Your energy system is primed; your technique just needs polish and discipline. You’re already showing the DNA of a strong HYROX athlete—now tighten the edges and let the run carry you through the gym.

Next races to target for you, Arne, are:

All Inclusive Fitness HYROX Cologne, 2026-04-16, Köln, Germany
Creapure HYROX Lyon, 2026-05-20, Chassieu, France
HYROX Rotterdam, 2026-04-15, Rotterdam, Netherlands

Plan your build with these in mind and keep the cadence steady. Use the Cologne race as your primary tune-up this season, then refine the exact transition sequences and wall-ball technique for Lyon and Rotterdam. A strong performance in the next events will come from fewer excuses and more precise execution—your run is strong enough to carry you through; now it’s time to finish those transitions with the same speed as your legs.
