Turn your goal time into pace (min/km), speed and split times to hit at each marker — for 5K, 10K, half and marathon.
At an even pace, your goal time translates into a pace (min/km), a speed and split times to hit at each marker.
Expected benefit: a clear pacing plan so you don’t go out too fast — and split times to memorise to stay on target.
Pick your distance and goal time to get your pace and splits.
Racing 'by feel' usually means blowing up mid-race: three kilometres too fast at the start cost you dearly at the end. An even pace, set to a realistic goal time, spreads the effort out. Knowing your split times at each marker gives you an objective reference during the race, instead of discovering too late that you went out too hard.
Even pacing is associated with the best endurance performances: most road records are run at a near-constant pace, often with a negative split (faster second half). Going out 5 to 10% too fast prematurely depletes glycogen and drives lactate up — the very mechanism of the wall. Number-backed split times turn that evenness into concrete targets, kilometre after kilometre.
Memorise 2 or 3 key splits (especially the halfway point) rather than the whole table. Aim for a first half very slightly slower than target: a few seconds/km of margin leaves room to finish strong. And be honest about the goal time — too ambitious a target makes every split untenable from the gun. When in doubt, cross-check it with the time predictor before locking in your pace.
