Vdotra: Pace & VDOT

Vdotra is the runner's calculator: from a recent race you get your VDOT, your training paces, your equivalent times at other distances and the splits for your track sessions. No account, no sign-up: open the app and calculate. PACES • Daniels and Gilbert VDOT from an official race time. • Daniels training paces: easy (E), marathon (M), threshold (T), interval (I) and repetition (R). • Track interval pace: enter your coach's session (for example 20 × 400 m in 1'40'') and see the pace per kilometre, the split every 100 m and the session total. • Switch between distance mode and track mode with one tap. • Extra tools: VO₂max (from a race, the Cooper test or heart rate), heart-rate zones, running economy and predictions. EQUIVALENTS • Projected times for 5K, 10K, half marathon, marathon and more, based on your current level. • Compare every projection with your personal records. • Choose the projection model: Jack Daniels or Riegel. • Environment simulator: estimate how heat, humidity and altitude affect your time. TRACK • Interval calculator: lane, distance and target pace, with splits and lap times. • 400 m outdoor or 200 m indoor track, with the real length of every lane. • Laps by time, laps by distance and lane differences. • Share your splits as an image. PERSONAL RECORDS (PR) • Log and update your best times per distance. • Follow your VDOT and PR progression in the athlete profile. ATHLETE PROFILE • Your name and photo in the app header. • Your VO₂max with your rating from the Cooper Institute reference tables. • Your key training paces always at hand. BUILT FOR TRAINING • Fields that format themselves as you type times, paces and dates. • Dark theme, light theme and a high-contrast mode for reading in the sun. • Metric or imperial units. • Keep-screen-on option and haptic feedback when tapping times. • English and Spanish. YOUR DATA STAYS YOURS Vdotra has no accounts and no servers of its own. Your records, profile and settings are stored encrypted on your phone, and you can export or import them as a backup whenever you like. Formulas are based on the VDOT of Jack Daniels and Jimmy Gilbert and on Peter Riegel's model. Vdotra is a training calculation tool; it is not a medical device.
