I have bypass tomorrow morning. I walked 3 miles a day with no issues. How long after surgery were you all able to walk your normal distance?

For me it was day 7 that I was hitting 10,000 steps a day. Day 4 I was about 3000 steps. Until today 17 days out I didn't have the strength to walk up steep hills. Just got cleared to do 30 minutes a day of outdoor cycling on flat roads starting tomorrow along with 10,000 steps a day.

I live on the side of a mountain, seriously. 150 feet of elevation from my house to the other side of the neighborhood. I used to do "the long loop" which was right around 2 miles, but sometimes went into the next neighborhood (Even more elevation changes) and did about 3-3.5 miles.

Post surgery, maybe a week out, I did the "short loop" which probably has 60 feet of rise and about 0.8 miles. I did that with a cane for a few days, but then stopped because it is so hot here right now (100+ degrees F). When I decided to walk later in the evening, I got up to 2 miles, but then started having some incisional pains and stopped for a while. About 2 or 3 days ago, I resumed the short loop again.

I don't know how much that helps, but I think it's better to go slow and not injure yourself, then to push yourself until something bad happens and then you're out weeks not doing anything -- but that's just me.
