Why does a sprinter warm up differently from a marathoner?

Power and sprint events need a thorough potentiation phase — strides, accelerations, or heavy singles — to fire fast-twitch fibres, so more time goes there. Endurance events need a longer easy raise and less explosive priming to avoid wasting glycogen.

How long should the gap before competing be?

The potentiation effect peaks roughly 5 to 10 minutes after a good primer and fades after about 20 minutes, so the schedule finishes the final primer a few minutes before your attempt and avoids long idle gaps that let you cool down.

What if I only have 15 minutes?

The tool scales every phase proportionally, so a short window still produces a balanced mini warm-up. Very short warm-ups compress the raise and mobility phases the most while protecting at least a brief potentiation primer.

Should I include my event-specific drills?

Yes. The potentiation block is where your event rehearsal goes — start blocks for sprints, approach runs for jumps, opener lifts for strength. Use the allotted minutes for the primers that most resemble your competition movement.

What is the Competition Warm-Up Time Calculator?

Enter the minutes until your first race or attempt and your sport type to generate a backward-planned warm-up schedule — general raise, mobility, sport-specific primers, and potentiation — each with clock times so you peak exactly on time. It runs free in your browser on Gera Tools, with nothing uploaded.

Turning up cold is a wasted performance; warming up too early lets you cool down before the gun. This calculator backward-plans a RAMP-style warm-up from your first attempt so each phase finishes exactly when it should.

How it works

The tool takes your available minutes and splits them across the RAMP phases, weighted by sport type:

Raise        — easy aerobic, lift temperature & heart rate
Activate/Mobilise — dynamic mobility and muscle activation
Potentiate   — sport-specific high-intensity primers

Sprint and power events bias time toward potentiation; endurance events bias toward a longer raise. Each phase is then placed on the clock by counting backward from your attempt time, with the final primer finishing a few minutes before you compete to catch the post-activation potentiation window.

Why the phases differ by sport

The RAMP framework is standard across athletic preparation, but the time split is not identical for every event:

Endurance (distance running, road cycling, rowing): A longer Raise phase — perhaps 15 to 20 minutes of easy aerobic work — elevates muscle temperature, opens capillaries, and primes aerobic metabolism. These athletes need less explosive potentiation and more time to settle into efficient movement patterns. Starting race pace too aggressively in the warm-up wastes glycogen and leaves the legs heavy.

Sprint and power (100m, long jump, discus, BMX racing): The Raise can be shorter, but the Potentiate phase must be thorough. Fast-twitch fibres do not activate fully without a period of progressively faster movement — accelerations, strides, bounding, or throws close to competition intensity. The post-activation potentiation (PAP) effect is the reason: a well-timed primer temporarily increases peak muscle force and speed.

Strength (powerlifting, weightlifting, strongman): The warm-up is built around working up through opener attempts. The Activate/Mobilise phase is critical — hip openers, thoracic rotation, and shoulder work prevent injury under maximal load — and the specific warm-up sets are the potentiation. Loading too heavy, too early, accumulates fatigue that blunts the opener.

Worked example: 45 minutes before a sprint race

For illustration, a 100m sprinter with 45 minutes available might see a schedule like:

Phase	Example activities	Duration
Raise	Easy jog, hip circles	~10 min
Activate / Mobilise	Dynamic leg swings, skipping, A-skips	~15 min
Potentiate	Accelerations, stride-outs, block starts	~15 min
Idle gap before the gun	Rest/strides to stay warm	~5 min

The final potentiation block ends roughly 5 to 8 minutes before the start, catching the PAP window without letting it fade.

Notes

Potentiation peaks around 5 to 10 minutes after a strong primer and fades by about 20 minutes, so avoid long idle gaps before competing. Put your real event rehearsal — blocks, approaches, opener lifts — inside the potentiation block. If a delay pushes your start time back, repeat a short activation drill to refresh the effect rather than standing cold at the line.
