4.8mile in 58 minutes

I run from my office back to home after work today. It has down hills in at least 1/3 of the distance. I run and walked back couple of weeks ago in 67 minutes and run and walked up hill to my office on Sept. 15th in 64 minutes. I planned to run back again within an hour last time and finally finished it today. I plan to run to office during this weekend within an hour, which means better performance since it was up hill.
I had a lot of physical activities today. 7:30-8:00am, swimming 1000m; 8:40-9:50am, tennis class; 10:00-10:30am, riding bicycle 4.8 miles to work; 6:15-7:15pm, jogging home from work; 8:00-9:00pm, playing softball co-ed game as catcher.
Hope I can recover soon enough, as I have jogging class early tomorrow morning.
