What do you need to figure out?

Three focused tools. Each one gives you an answer you can act on.

Answers, not more research

Useful enough to change your next run.

No generic top-ten lists. No unexplained score and a hundred options. Runner Toolkit narrows the choice, shows the tradeoffs, and gives you a clear next step.

01Personalized

Built around the run, runner, and constraints rather than a universal ranking.

02Explainable

Every recommendation includes reasons, assumptions, and tradeoffs.

03Independent

Retailer relationships never decide what gets recommended.

Runner Toolkit Injury Rescue

Injured mid-training? We'll get you back to the start line.

It works with the plan you're already on: Higdon PDF, Garmin Coach, your coach's spreadsheet, or ours. A short symptom check grades the injury the way a professional would, then the remaining weeks are rebuilt around a careful return, with an honest answer when racing isn't the right call.
