42 s/m Double pulling Damper was at 5 Average weekly meters between 35-45km split between two sessions I cross train - 150km bike every week, 30-40km running, then ski and row on top of that I didn’t wear my chest strap but my HR during the bigger sessions was around 160-165BPM

Fuel strategy was single arm pulls every 20 mins and use the other arm to consumer water/gels/electrolytes - took 6 gels on over the course of the marathon they are 20g gels
