Daniel Rowland and Mikael are back for another research roundup with four recent studies. What blood biomarkers do and do not tell you about training load in elite triathletes, why two athletes with the same VO2max can have very different thresholds, what actually predicts running injuries in a cohort of 5,200 runners, and whether supersets deliver the same strength gains in a third less gym time.

If you are focusing on improving your FatMax in 2026, you’re likely wasting time and money. Not only is fat a more expensive substrate to burn than carbohydrate (you get less energy for the same amount of oxygen by oxidising fat), but the Fatmax number you see in your lab report is mostly noise and very little signal.
In today’s episode of That Triathlon Show I’ll explain exactly why that is, but I’ll also give you a tool to evaluate any test or measure that you might (or might not) want to be tracking, from Time Trials to VO2max, HRV and various biomarkers like ferritin and testosterone.
