Slog
Running/endurance term; genuine trade/athletic vocabulary
A combination of the words job and slow, the term for a run or portion of a run when your pace slows to that of a quick walk usually due to exhaustion, a loss of motivation, or physical distress. Usage patented by laura @ the gluten-free treadmill, Susie @ SuzLyfe, and Mike @ Running Around the Bend.
By the end of the marathon, I was reduced to slogging through the last mile because I was so tired.
