The science
Built around RED-S awareness
RED-S — the health fallout when you're not eating enough to cover your training — doesn't announce itself. It builds gradually through sustained fatigue, low mood, high perceived effort, and suppressed appetite, quietly weakening bone and disrupting hormones long before a stress fracture or missed period makes it obvious. The 2023 IOC consensus statement made RED-S a recognized priority in athlete health. Because most running injuries build over weeks rather than from a single event, the daily signals matter — DARS tracks the indicators that help you and your healthcare provider spot the drift early. DARS is a wellness tool, not a diagnostic instrument.
44%
of female athletes have low energy availability — the driver of RED-S (Lodge et al., Sports Medicine, 2024)
49%
of male athletes have low energy availability, too — RED-S is not a women-only issue (Lodge et al., Sports Medicine, 2024)
72%
of running injuries are overuse-related, not acute (Nielsen et al., Garmin-RUNSAFE, 2024)
30–50%
bone-stress-injury rate in female athletes with two or more Female Athlete Triad risk factors — vs 15–20% with one, over the study period (Barrack et al., AJSM, 2014)
Science-grounded methodology
DARS is grounded in the IOC 2023 RED-S Consensus Statement, the LEAF-Q, and the BEDA-Q screening tools — the same frameworks used in elite sport and clinical research. D5 hard-override floors are designed to avoid clearing athletes to train through likely RED-S or acute illness.
