Q&A #109 - Running race pace and training zone calculators; Estimating your run threshold pace; How to use session-RPE Do calculators that estimate and "equivalent race pace" (e.g. from a 10k to a marathon) actually work?  What about the recommended training paces from such calculators? How can you estimate your running threshold pace (without doing a one-hour time trial)? What are best practices for using session-RPE?    LINKS AND RESOURCES: Scientific Triathlon website Coaching Training Plans Q&A episode archive McMillan Running Calculator Jack Daniels' VDOT Running Calculator Scientific Triathlon Training Zones Calculator A New Approach to Monitoring Exercise Training (Foster et al. 2001) How World Tour cyclists train, and a discussion on training load with Teun van Erp, PhD | EP#250   SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
