One continuous effort, not 16
The most common mistake is treating the race as 16 separate events you sprint and recover from. It isn't. The clock never stops, so every hard surge on a run or station is borrowed energy you repay later, usually at compound interest in the back half.
Frame the whole thing as one 60-to-90-minute steady-state effort that happens to change shape every few minutes. Your job is to find the single sustainable intensity you can carry through the final wall balls, then refuse to exceed it early. Discipline in the first third is what makes the last third possible.
A target run pace you can hold compromised
Your race run pace is not your fresh 5K pace. It is the pace you hold with fatigued, station-trashed legs. A useful rule: take your open 1 km pace and add 30 to 60 seconds. Run a fresh kilometer in 4:30 and you should plan race kilometers at 5:00 to 5:30.
Train it specifically with compromised-running drills: 20 wall balls or 20 walking lunges, then immediately run 400 to 800 m at goal pace, repeated six to eight times. You are teaching your legs to find rhythm under fatigue. The pace you can repeat without slowing on rep six is your real race run pace.
Which stations to push vs survive
Not all stations cost the same. The SkiErg and rower are aerobic and forgiving; settle into a strong-but-controlled split (women near 2:15 to 2:25 per 500 m on the row, men near 1:55 to 2:05) and let your legs recover for the next run. These are stations where smoothness beats violence.
The sleds, farmers carry, sandbag lunges, and burpee broad jumps are the survival stations. They spike heart rate and trash the legs you need to run on. Move steadily, keep micro-rests short and pre-planned, and never red-line. Wall balls are the exception worth a calculated push because the race ends right after them.
Negative-split mindset
Even splits are the floor; a slight negative split is the goal. Aim to run the second half of the race no slower than the first, ideally a touch faster. The only way to do that is to start at an intensity that feels almost too easy in the opening two runs.
Concretely, if your goal kilometer is 5:15, run the first two at 5:20 to 5:25. That five-to-ten-second buffer feels like leaving time on the table. It isn't. It is the deposit that funds a strong finish instead of a death-march final 2 km.
Effort cues per segment
Anchor each segment to a perceived-effort number on a 1-to-10 scale. Runs sit at a 7: conversational-plus, controlled breathing, never gasping. SkiErg and row sit at 6 to 7, strong but recoverable. Sleds and carries sit at 8, hard but with something in reserve.
Use breath as your governor. If you cannot speak a short three-word phrase at the end of a run, you are over pace and bleeding the back half dry. Build cadence over speed on the runs: a quick 175-to-185 step rate keeps you moving when stride length collapses from fatigue.
Pacing the back half
The race is decided from station five onward, when the legs are cooked and the runs feel uphill. This is where even-split discipline pays out. Hold your number, shorten your stride, lift your cadence, and refuse to walk the transitions.
Break the big-rep stations before you have to. On 100 wall balls, a planned scheme like 25-20-20-20-15 with five-second resets keeps you off the failure-and-flail cycle that costs a full minute. Pre-deciding the breaks removes the in-the-moment negotiation that fatigue always wins.
Use the simulator to test a plan
A pacing plan is a hypothesis until you run the numbers. Plug your run pace, station splits, and transition times into the finish-time simulator and watch the projected total. Adjust one variable at a time: what does a 10-second-slower run pace cost? What does a faster row buy?
This is how you find your limiter before race day instead of discovering it at kilometer six. The simulator turns a vague goal into a segment-by-segment script you can rehearse, so the race feels like a plan you are executing rather than a problem you are solving on the fly.
Race-day pacing checklist
Lock the plan into a few non-negotiables you can recall under stress.
Run the first two kilometers five to ten seconds slower than goal pace. Keep the row and SkiErg at a 6-to-7 effort, never sprinting. Pre-decide every break scheme on wall balls, sandbag lunges, and the carries. Keep transitions brisk but never a sprint. Save the calculated push for the final station, and only there.
