Live average pace from distance and finish time, then an even-split race ladder - so a goal finish never pretends to be every kilometer already run.
Educational running sketch. Finish ≠ splits. Not medical advice, race strategy clearance, or a GPS substitute.

01
A finish time is the story the clock tells at the line. Average pace is that story divided by distance. Splits are the kilometer- or mile-by-mile plan that would add up to the same finish if every mark were perfectly even.
This page’s framing is Finish ≠ splits. The panel still prints a clear average pace, then refuses to pretend that one number is already a race plan. Hitting 1:45 for a half marathon is not the same cognitive task as hitting each kilometer on time when the course rolls and the crowd surges.
That is intentionally different from the calorie calculator’s Pace ≠ crash framing, which is about weekly weight-change speed versus metabolic floors - not running splits. Here “pace” means clock speed on the road or track.
Use this tool to translate a recent run into pace, project that pace onto common race distances, and sketch even cumulative marks before you write them on your arm.
Decision framing: “What even splits match this finish?” - not “Did I already race the perfect kilometer?”
02
Pace is time per unit distance - usually minutes per kilometer or minutes per mile. Speed is the inverse story in km/h or mph. Both come from the same inputs: distance and total time.
The panel accepts hours, minutes, and seconds so a marathon finish does not get jammed into a single “minutes” field. Distance can be kilometers or miles; pace display can be toggled independently so a metric race goal can still show min/mi if that is how your watch speaks.
Race chips hold your average pace constant and ask what finish that pace implies for 5K, 10K, half marathon, and marathon. That is a projection - not a prediction that you can hold the pace as distance grows.
03
The unique affordance is the even-split race ladder: cumulative elapsed times at each kilometer or mile mark for the focused distance, plus a finish rail with tick marks. Tap a race chip to load that official distance and rebuild the ladder.
That ladder is unlike recent renewals: not a salary cadence mirror, not a one-rep-max % intensity ladder, not a rent-vs-buy horizon crossover strip, and not a fasting day clock. One interaction for Finish ≠ splits.
Even splits are a clean baseline. Many athletes prefer slight negative splits or course-adjusted plans. Heat, hills, and aid-station chaos will move the real clock - the ladder is literacy for planning, not a referee.
Try the Half goal preset, then tap Marathon on the race chips - same pace, much longer finish, longer split list.
04
Road races worldwide are measured in kilometers; many U.S. training cultures still think in miles. The panel keeps both distance unit and pace display so you can mix carefully - for example, a 10K distance with min/mi pace readout.
Half marathon and marathon chips use standard distances (21.0975 km and 42.195 km). Custom distance leaves the focus on whatever you typed - useful for tempo segments and odd race routes.
GPS watches disagree slightly with certified courses. Treat calculated splits as a plan sketch and confirm with course maps when the result matters for a goal race.
05
Pace alone does not describe effort. Heart rate, perceived exertion, and terrain change what a “easy” number feels like. Pair pace literacy with recovery and progressive overload - especially if you are new to running.
Session energy sketches belong on the calories burned calculator. Strength work that supports running economy can use the one-rep max calculator. Zone-style cardio context lives on the target heart rate calculator.
Weekly nutrition pace (a different “pace”) is the calorie tool’s job - do not confuse Finish ≠ splits with Pace ≠ crash.
06
Example A · Easy 5K. Preset: 5 km in 30:00. Read min/km, then scan the even-split ladder for each kilometer mark.
Example B · Tempo 10K. Preset: 10 km in 50:00. Tap Half and Marathon chips to see how the same pace projects - Finish ≠ splits still applies when distance grows.
Example C · Half goal. Preset: 21.0975 km in 1:45:00. Use the ladder’s cumulative times as arm-band candidates, then adjust for hills.
Example D · Mile training. Preset: 3 miles in 27:00 with min/mi display. Custom focus keeps your segment distance while chips still project road-race finishes.
After presets, enter your own distance and finish. Share only when units, time, pace display, and race focus match what you intend to send a training partner.
07
Most pace harm is confusing average with plan - and confusing running pace with diet “pace.”
08
Share links snapshot distance, unit, time parts, pace display, and race focus. Live typing never rewrites the address bar.
09
Stop here for Finish ≠ splits literacy: average pace, race projections, and even cumulative marks. Hand off when the question is energy, strength, heart-rate zones, or weekly nutrition pace.
10
A finish time (or the average pace that produces it) is one number for the whole race. Splits are the kilometer- or mile-by-mile clock plan that adds up to that finish under an even-pace assumption. This page’s framing is Finish ≠ splits so a goal time is not mistaken for how you actually run each marker.
It takes your computed pace and projects finish times for 5K, 10K, half marathon, and marathon, then lists cumulative even splits for the focused distance. That race ladder is the unique affordance - different from salary cadence mirrors, one-rep-max intensity ladders, rent-vs-buy crossover strips, or calorie Pace≠crash dials.
Even splits are a clean planning baseline. Many runners use slight negative splits (second half faster) or course-adjusted plans. Hills, heat, and crowding break even math - treat the ladder as a sketch, not a coach.
Use the pace display toggle. Distance can stay in km or miles independently; the calculator converts through kilometers under the hood so speed and race chips stay consistent.
No. Educational only. Increase training gradually, respect injury signals, and seek qualified coaching or medical care when needed. A pace number does not replace race-day judgment.
No. Values hydrate from the URL on load; the address bar updates only when you use Share or Copy.

Average pace explains the finish clock. The ladder shows even cumulative marks - a plan sketch, not a promise you will hit every split on race day.
