strive.ai brings advanced analytics to the Strava app ecosystem. The analytics aim to enhance the Strava's user experience through data science and help athletes understand what factors are influencing their performance. Features are described below: Strava Experience 1. Segment Achievements stack ranked by watts per kilogram for cyclist and runners who train with power meters. 2. Find other athletes who have similar watts per kilogram. 3. Ability to predict probability of Segment PR based on weather forecast and past athlete performance. 4. Predict which bike was used on Ride activities. Performance Analytics 1. Tracking of peak thresholds over [1, 5, 20 and 60] minute periods for heart rate, bike power and run power. 2. Tracking of running best efforts over 400m, 800m, 1600m, 5000m and 10000m. 3. Identify what "Factors" are influencing your peak thresholds / best efforts up or down. Standard version includes factors obtained from Strava API (e.g. cadence, temperature, altitude, activity type) while premium WILL include "Factors" gathered from sources outside of Strava (e.g. Weather, Apple Health, Garmin Connect). 4. Calculation of Training Peaks Marks (TSS, IF and NP) for cyclists with power. 5. Trend reporting of key metrics (e.g. peak thresholds, IF, TSS, NP). 6. Notification of data anomalies from bike and running power meters. 7. Ability to flag thresholds as anomalies to remove them from your performance history.

The CORE Thermal Sensor accurately measures your core body temperature and thermal strain on your body – continuously and non-invasively. Thermal data and insights are critical for facilitating safe and effective heat training and for performing optimally on race day. Designed for athletes at all levels, CORE will help to improve your training and performance in your personal adventures or races. IMPORTANT: The CORE app is designed to work with the CORE device which you can order at www.corebodytemp.com Here's how it works: • Set up your CORE sensor: connect your heart rate monitor and sports devices for optimal sensor use. • Measure your thermal vitals during training: mount the newly designed clip on your heart rate strap and snap in the CORE sensor. Shake the sensor to wake it up, wear it and track your thermal data. • Core body temperature: the interior temperature deep in your body, including organs and other tissues. A critical measure during sports, it can reach up to 40°C (104°F) during vigorous activity in hot environments. Be aware that hotter is not better – cooler is faster. • Heat Strain Index: A combination of your core body temperature and skin temperature representing the thermal strain on your body. The real-time feedback on how hard your body is working to stay cool, delivering a value from 0 (no heat strain) to around 10 (extremely high heat strain). • Heat Zones: Your Heat Strain Index divided into easy-to-use zones. Heat Zone 3 will likely lead to a performance loss, BUT it is the needed stimuli to create adaptations in your body. During heat training, strive for time in heat zone 3. During racing, stay cool and prevent a performance loss by staying in heat zone 1 or 2. • Heat Training Load: a cumulative daily metric of the heat strain on your body. A daily value of 10 out of 10 indicates ideal contribution to heat adaptations. More is not always better! • Heat Adaptation Score: Track your heat adaptations over time with effective heat training. Get a heat champion to perform best in the heat. Long-term heat training will most likely lead to improvements also in cool conditions. • Add your passive heat training: Supplementing your active heat training or general training with passive heat exposure in a sauna or hot bath. You can track your sessions in the app manually, contributing to your heat adaptation score. NOTE: do NOT take your CORE sensor into the sauna or hot environments. What else you can do in the CORE app: • Dig into the details: See a breakdown of your thermal data, and even see trends across days, weeks and months. • Share your CORE metrics with your friends through the social sharing feature, earning more kudos and likes • Connect your connectivity accounts (e.g. Garmin) to directly synchronize your data after the training. • Update your sensor to the latest firmware ensuring having the best sensor functionality. Note: CORE provides products and services designed for general fitness and training purposes. For accurate measurement readings during sports, a connection to a heart rate monitor is necessary. CORE products and services are not medical devices, not intended to treat or diagnose any disease, and should not be used as a substitute for professional medical advice, diagnosis or treatment.
