running

My sister challenged me to an organized 5km race on September 16th being held in a nearby town. I started my training last night. The loop below is just about exactly one km, so I did five counter-clockwise laps starting on Forest Hill where the yellow/blue line ends and the blue line begins.


Lap 1: Run blue, walk yellow, run blue until orange, sprint orange, walk yellow
Lap 2: Run blue, walk yellow, run blue until yellow, walk yellow
Lap 3: Run blue, walk yellow, run blue until orange, sprint orange, walk yellow
Lap 4: Run blue, walk yellow, run blue until yellow, walk yellow
Lap 5: Run blue, walk yellow, run blue to end.

I don't have a stopwatch yet, so I don't know how long it took, however, based on previous years runs, to place in the top 10 I need to run 5km in 20 minutes or less. To place in the top 5 I need to run it in 19 minutes or less, and to place in the top 3 I need to run it in 18 minutes 50 second or less. My goal is to make it into the top 3.
