Description

This week's questions:

  1. How should I adjust my nutrition if I'm training twice a day?
  2. I’m constantly getting colds during heavy training periods – could my nutrition be a factor?
  3. What are the non negotiables for maintaining muscle mass when trying to amp up running training in distance (20km-ish and heading for marathon) and intensity (on separate days) Im weight training aiming for maintenance 3x per week and running 4x per week (intervals, tempo, zone 2,long run.) Is weight staying stable the best metric to measure?
