How to use AidSplit

1. Choose the race type that best matches the day ahead: 5K, 10K, half, marathon, or long supported trail race.
2. Add the conditions that most affect execution: weather load, course profile, aid-station spacing, and what you can realistically carry.
3. Be honest about your own habits: stomach sensitivity, start discipline, training confidence, and whether walk breaks are useful protection or not.
4. Submit the form to get a recommended posture, a four-phase execution plan, aid-station actions, fuel timing cues, and a copyable race brief.
5. Rerun the scenario if the weather changes, the course looks harder than expected, or you decide to carry more fuel.

What the output means

• Steady split means the day supports a controlled, even effort with light-to-regular fueling.
• Cautious start means the first part of the race should be protected so heat, hills, or pacing habits do not blow up the middle.
• Run-walk guardrails means the safest plan is to use deliberate resets before fatigue becomes a spiral.

Good use cases

• The first warm race of the season
• A route with awkward aid-station gaps
• A long race where you keep forgetting to eat or drink early enough
• A comeback event where discipline matters more than ego

AidSplit is meant for planning and communication. Always adapt to event guidance, medical considerations, and real conditions on the day.
