T_mar: marathon time (hours); vMar: mean speed for the marathon (km⋅h⁻¹), vMar_%vSV_max: mean marathon speed as a percentage of the speed at maximal stroke volume during the incremental test; vMar_%vV̇O_2max: mean marathon speed as a percentage of the speed at maximal oxygen uptake during the incremental test.
