OPTIMAL Running is an online performance analysis service for runners. It does not require a lab, blood tests, or specialist equipment. Instead, users complete a 20-second sprint plus 2β4 all-out timed runs on a 400 m track or flat road, then submit their results to generate a personalized 6-page PDF report. The site does not explicitly describe it as an AI tool; it is more accurately a sports performance analysis service based on mathematical/metabolic models.
The report covers metrics such as VOβmax, VLamax, running economy, critical speed, aerobic threshold, and fat oxidation capacity, and generates 7 personalized pace and heart-rate training zones. It also predicts race performances from 800 m to the marathon, and provides carbohydrate fueling strategies for the half marathon and marathon, including carbohydrate use at race pace, total fueling amount, gel timing, and split-by-split planning. The Full plan measures anaerobic capacity directly via a Dβ² test, offering higher accuracy.
Pricing is a one-time payment: Quick Β£19.99, Standard Β£24.99, and Full Β£29.99. All three tiers deliver the same 6-page report; the differences are the amount of data required and the level of accuracy. Payments are processed via Stripe, and the site states that it does not store card information. After data submission, the report is usually sent by email within 24 hours and can also be downloaded from the dashboard.
Its strengths are low cost, a much lower barrier than lab testing, and outputs that are directly useful for training, race prediction, and marathon fueling. Data is subject to automated quality checks, including cases where RΒ² is below 0.990 and physiological plausibility checks. The limitations are also clear: accuracy depends entirely on whether the user truly completes maximal-effort tests; the estimates do not have clinical-grade precision; and the service does not constitute medical advice. The site also does not show API support, automatic syncing with third-party platforms, Chinese-language reports, or app-based functionality.
It is best suited to runners with some training background who can independently complete field tests, especially those preparing for a half marathon or marathon, club runners, and serious runners who want to retest periodically. Beginners or anyone with health risks should be cautious about all-out testing. There is no information in the main site content about access from mainland China, so availability is unknown. Payments are mainly in GBP via Stripe, so users in China may need to consider whether their bank card will work. Alternatives include lab-based sports testing, assessments by running coaches, and training-zone or race-prediction features in ecosystems such as Garmin, Polar, Coros, and TrainingPeaks.
