Still riding the bike 30-40 minutes a day. Strengthening one day a week in the gym (90 minute workout including plyometric jumping and even landing on one leg :-), leg extension, squat machine, hip adduction/abduction machine, stair master for 25 minutes). 30 minute walk few times a week.
As far as running goes, no pain what so ever. I'm doing interval type training at 7 mph on the treadmill and my running endurance makes my PT guy laugh because after 6 minutes I can't breath and he has to grab a towel for me to catch all the sweat! ha. I'm not a runner and never plan to get into it, so long distance endurance isn't a priority of mine.
Looking back, I think the milestones as far as time goes and progress is definitely 6 months, 1 year, and 1 1/2 years. I'm at 15 months and it feels a little better than when I was at 12 months, so weird how it works like that. Tortoise definitely wins the race and there is really no point in pushing it; don't let human emotion and your competitiveness get in the way of safely progressing :-)
