Ergometer Pace and Distance Tool
Every Concept2 RowErg in the country shows a 500m split, the projected time over half a kilometre at the current effort. Drop that figure into the boxes below and the tool returns watt output, an hourly kilojoule rate, the calorie estimate, and the projected finishing time across every test piece your programme actually runs - from a flying half-kilometre through the Olympic distance, the standard winter benchmark, the long aerobic test and on out to the marathon piece your captain put on the shed wall.
A one-screen converter for Aussie ergometer testing
A one-screen converter that takes the split off a Concept2 monitor and turns it into the watt, kilojoule and projected-split numbers every Aussie crew leans on to plan ergometer testing. The watt figure comes straight from the C2 cubic relationship (the published equation that ties pace to power). Longer pieces use the Riegel endurance fade, so a sharp 2k projects forward into realistic 5k, 6k, 10k or pre-Yarra targets. AGSV and CAS coaches lean on it to set squad-wide goals, masters scullers use it to reverse out age-graded targets, and Year 10 rowers use it to work out the actual split they need to hold.
Inputs
Most squad-grade efforts sit between 1:25 (Boat Race finalist) and 2:30 (first ergometer of the season).
Jump straight to a typical squad band
Indicative bands: social masters around 100-200W; trained openweight squads 250-350W; King's Cup-grade and AIS scholars routinely above 400W.

Method behind the numbers
Reading a 500m split off the C2 monitor
Split is the projection metric every Concept2 ergometer in an Aussie boatshed runs on. It is the finishing time the monitor predicts for the next 500 metres if the upcoming strokes match the recent strokes. Smaller number, faster boat. Pulling 1:42.5 means the next half-kilometre is on track for 1 minute 42 and a half seconds, and a flat-out 2k at the same effort would land on 6:50. Schools squads and AIS programmes capture splits stroke-by-stroke because the season-long trend exposes things a paper logbook quietly hides. Squad-wide ergometer telemetry only delivers when the data is captured automatically.
Turning split into watts on a Concept2 RowErg
Concept2 ties pace to power through a single cubic relation: P = 2.80 / (sec_per_500 / 500)^3. The cube on the denominator is brutal. Halve the pace number and watt output goes up by a factor of eight, which is why the climb from a 1:50 toward a 1:40 costs roughly four times the energy of the climb from a 2:00 toward a 1:50, and why no amount of grit clears the last few watts without a sustained aerobic base behind it. Aussie programmes that benchmark on watts (rather than leaning on split in isolation) spot lightweights overreaching on short pieces and heavyweights coasting on long ones, then feed the corrected scores into the squad session record.
Where the kcal/hr figure on the C2 screen comes from
The Concept2 monitor lifts watt output into an hourly kilocalorie estimate via kcal/hour = 4 x watt_output + 300. The standing 300 represents resting metabolism during exercise. Identical arithmetic drives the kcal column on this tool, so the displayed value matches the on-screen reading mid-piece and ties into the weekly volume totals the coach tools dashboard rolls up across a Penrith camp or pre-Yarra block. Genuine burn rate shifts with body mass, muscle composition and shed temperature, so use the figure as a session-to-session training-load proxy rather than a dietitian-grade calorie ledger.
Swapping pace for time and back again
A converter does two jobs at once. Hand it a split and it returns finishing times across every test distance. Hand it a finishing time at one distance and it returns the average split that produced it. Both directions reduce to one line of arithmetic - finishing time equals split multiplied by the number of 500-metre segments in the distance. Worked through at a 1:48 setpoint, that lands at 7:12 over the Olympic 2k, 18:00 across 5k and 21:36 across the 6k winter test. The form above runs both directions instantly and stamps matching watt and kJ figures alongside each row, so the complete test sheet builds itself without flicking between tabs.
Behind the longer-distance predictor
For longer pieces we lean on the Riegel endurance relation - projected time equals the base time multiplied by the distance ratio raised to a 1.06 fade exponent. That exponent is the canonical fade observed across running, swimming and rowing test data, and lines up well with Aussie ergometer scaling in practice. Treat the output as the opening conversation, not the verdict. Lightweights and junior rowers usually fade harder than the curve suggests, while big aerobic engines (think a 95kg M8+ stroke seat) hold pace better than the model predicts. Use the projection to open the chat with the coach about realistic 6k or Head of the Yarra goals, then sharpen it once a real long piece is in the book.
The five intensity bands an Aussie programme uses each week
AIS protocols, the Penrith camp programme and most AGSV/CAS/GPS schools all run a five-band weekly structure pegged to the 2k split. Numbers below are typical setpoints (rate, then pace offset relative to your 2k):
- UT2 - steady aerobic: rate around 18-20, sit roughly 12 to 15 seconds slower than race pace per 500.
- UT1 - firm aerobic: rate around 22-24, run about 8 to 10 seconds slower than race pace per 500.
- AT - anaerobic threshold: rate around 26-28, hold within 4 to 5 seconds of race pace per 500.
- TR - transport (race pace): rate climbs into the 30-34 band, pace lands on the 2k split itself.
- AN - anaerobic: rate above 36, splits drop below 2k pace, usually short pieces only.
Once the 2k split is locked in, every other zone falls out of it. The standard fix when the 2k is months stale is to drive a recent long aerobic piece through the predictor table, take that as the working figure, and feed it into the training pace tool to lift out the splits, rates and watts a coach actually writes on the whiteboard.
Indicative ergometer marks across the standard test distances
Indicative numbers drawn from real Aussie programmes, framed for openweight male rowers. Elite squads typically shift each column down by anywhere from five to fifteen seconds per 500m. Openweight female benchmarks usually run around eight to twelve seconds outside these figures. Masters and junior categories need to be read alongside the Concept2 age-grade tables, not directly against the open numbers:
- 500m flying piece: club rowers chase 1:25, state-squad shortlist around 1:20, internationals under 1:15.
- 1k: open club around the 3:10 mark, state squads inside 3:00, international standard inside 2:50.
- 2k Olympic test: open-club rowers chase the 6:50 mark; sharp AGSV, CAS or GPS 1st VIII rowers (and uni 1st VIIIs) push under 6:30; King's Cup squad shortlists open at 6:15; national elite men sit beneath 6 minutes flat.
- 5k aerobic test: open clubs target 18 minutes flat; university and 1st VIII schools squads chase 17; national-level openweights inside 16:30.
- 6k winter test: open clubs around 22 minutes; uni and schools 1st VIIIs aim for 20:30; Boat Race and national squads under 19:30.
- 10k base piece: club rowers around 38 minutes; uni and schools 1st VIIIs around 35; national openweights inside 33:30.
Rowing Australia's squad standards sit in the same neighbourhood as the figures above; what changes between programmes is squad depth, not the watts on the flywheel. Schoolboys aiming at Head of the River or the Australian Schools Championships typically benchmark against the previous year's 1st VIII trial sheet from their own school, while open-age athletes calibrate to King's Cup ergometer trials and Australian Boat Race selection. Masters crews should always push the raw split through age-graded percentiles before drawing conclusions. For a percentile-band placement with bodyweight and age handicapping built in, jump straight to the ergometer score percentile tool. And for back-solving a credible Olympic-distance goal off a long aerobic piece, the 2k projection utility is the next stop.
A single split is a sum. A whole VIII across a season is a system.
A single split is a pocket-calculator job. A whole squad's ergometer history across a Penrith camp, a Yarra block and the build to Schools Champs is a database problem. Row HQ writes every score against the right athlete the moment it lands, so the coach pulls crew lineups from live data, catches a sculler going backwards via administrator-side dashboards, and stops trawling WhatsApp threads or last fortnight's spreadsheet to find a PB.
Have a look at the OTRC case study for how a real club turns ergometer numbers into selection-night decisions, work through the practical guide to getting actual value out of squad ergometer data, or step through the session-tracking features that record every split with zero coach data-entry. Set that next to the shared-spreadsheet routine still in use across most boatsheds and the case writes itself.
Frequently asked questions
So what does the 500m split number actually mean?
It is the rolling projection the C2 monitor shows in mm:ss.t format - so a reading of 1:42.7 means one minute, forty-two seconds and seven tenths. The number forecasts the finishing time over the next half-kilometre at the current effort. Smaller number, faster boat. Aussie programmes anchor zones, racing plans and athlete comparisons on the split because it is unambiguous, repeatable across crews, and converts straight to boat speed the moment the squad pushes off at Penrith or onto the Yarra. Squads that capture every session split automatically spot slumps weeks before they surface in regatta margins.
Working out the watt figure from a given 500 split?
Concept2 publishes the relationship as watt output equal to 2.80 divided by the cube of pace-seconds-per-500 normalised by 500: P = 2.80 / (sec_per_500 / 500)^3. Try the equation at 1:55 (115 seconds total): the maths gives you somewhere near 230 watts. Drop to a 1:35 (95 seconds total) and the figure climbs to roughly 408 watts. The cube term on the denominator is what hurts. Halve the pace number and watt output multiplies by eight. Which is precisely why dragging the split number down from 1:50 toward 1:40 is a fundamentally different ask than the climb from 2:00 toward 1:50. The tool runs the canonical equation, so the watt column reconciles cleanly with the monitor in front of you and with the values piped into your squad's coach dashboard.
Where should an Aussie rower expect a 2k erg score to land?
The honest answer is it depends on weight, age, gender and training history. A fit social rower under 7:30 is doing well. Competitive openweight men typically chase under 6:30 and lightweights under 7:00. Elite openweight women land around 7 minutes flat, elite openweight men around 6 minutes flat. Strong U19 athletes can match senior figures given a proper programme behind them. AGSV, CAS and GPS 1st VIII rowers usually sit between 6:20 and 6:45 by the time selection comes around, while masters athletes should always run the score through the Concept2 age-graded tables before any of those open columns are meaningful as a comparison. For a deeper look at how to actually act on these numbers across a season, work through the Row HQ playbook on squad-wide ergometer telemetry.
Translating an Olympic 2k erg score into projected long-distance pace?
Splits drift outward as the piece gets longer. Most Aussie squads work with a rough rule that splits open up by around five seconds per 500 every time the distance doubles. So a 1:42 at 2k usually lands around 1:47 over 5k and around 1:49 across 6k. The predictor table sharpens that estimate using the Riegel relationship: predicted = base * (new_distance / base_distance)^1.06. The 1.06 exponent is the canonical endurance-sport fade and tracks Australian ergometer testing well across local programmes. Junior rowers and lightweights typically fall off faster than the model, while big-engine heavyweights hold pace better, so calibrate accordingly when sizing up a Yarra effort off a recent sharp 2k.
How does the kcal/hr number on the C2 monitor get calculated?
Concept2 derives the per-hour kilocalorie figure with kcal/hour = 4 x watt_output + 300. The fixed 300 stands in for basal metabolism during exercise. Identical maths runs in this tool, so the kcal estimate aligns with the on-screen reading during a piece. Treat it as approximate. Real burn shifts with body composition, shed temperature and warm-up state, but the result is repeatable enough across sessions to act as a relative training-load metric when planning fuelling through a heavy King's Cup build week.
What 5k score should an Aussie squad rower be chasing?
Under 19 minutes across the 5,000m piece is a respectable mark for a fit social rower. Open-club male openweights tend to push beneath 18, university and schools 1st VIII athletes inside 17, and national-level openweights step inside 16 minutes 30. The equivalent for openweight female athletes typically runs around a minute to a minute and a half back at each tier. The 5k usually rates in the 24 to 26 stroke band and sits a touch below anaerobic threshold. Quick check: the average 500-segment pace on a 5k typically lands eight to twelve seconds outside the matching Olympic-distance split.
Where does a good 6k erg score land in Aussie programmes?
For a fit social rower, breaking 22 minutes over 6,000m is a respectable mark. Open-club squad athletes typically push under 21 minutes, university and schools 1st VIII rowers under 20, and national-level openweights with Kings Cup or Australian Boat Race selection in view sit under 19:30. The 6k sits in the winter benchmark slot across most senior Aussie programmes, rated 24 to 26 strokes per minute. Pencil the average pace per 500 on a 6k as roughly ten to twelve seconds outside the equivalent Olympic-distance pace. Push a recent 6k score through the predictor table to reverse-engineer a credible 2k goal.
