I'm still unsure of if and when I'll be able to come back this year. This has not changed in the past couple of weeks. I'm working hard on the bike and the elliptical machine, but I'm just not there yet. While I continue to progress, I do not want to push myself to come back sooner and ultimately jeopardize the health of my knee and suffer a setback. However, I still remain optimistic.
