Key topics in this episode:

Question #1: Should Training Stress Score (TSS) be adjusted for extreme environments?

• Does actual training stress change with heat or cold enough to alter TSS?
• After rides on technical or rough courses, examine TSS from HR or Power (hrTSS vs TSS). Go with the higher one because HR may reflect effort while not pedaling.
• LSS (Life Stress Score) - high/medium/low subjective measure. LSS does not increase TSS on stressful work day, but LSS provides context.
• When stress is higher (TSS, hrTSS, or LSS), give grace, add recovery. 

Question #2: During long rides, I consume my first energy drink after 90 minutes, and then I can ride harder than I could at the beginning. Does anyone know why? 

• Effect of sugar and caffeine (i.e. from Red Bull, Monster or sports drink) on energy and focus in short term
• Benefits of consuming calories earlier and more frequently during long rides
• Nutrition recommendations specific to early morning and after-work training sessions.
