If you pull the ring facing the slog, you'll waste precious milisceonds turning around, then starting to run.
When you are up to pull the ring, keep your back to the slog. After pulling the ring, BEAT FEET. YOU'll manage to reach the right gap before the slog. Don't forget to make a run-jump. The slog won't follow you.
