Fitting in Fitness: Registering for a 5K

I wanted to fit in fitness this morning while DS is with his father. I did the same trail I did a couple of weeks ago; here are the results:

Sorry my camera is out of focus. The trail is 3 miles and unlike the last time, I did add in some running; not a lot. It took me 41 min and 49 sec and it says I burned 618 calories??? Not sure that is correct, something may be off with the heart rate monitor.

I plan to do this again on Tuesday, with a goal of 40 minutes; so got to bump up running. I want to register for a 5K this week.

Added note: This trail has hills and quite a few of them.
