2 min. warmup with a 5 min hard Garmin Benchmark run

I started a 5k training program through Garmin. Today was a 5 min benchmark run, (a 5 minute as hard run) that will be used to tailor my running program. The workouts are automatically downloaded to the Garmin watch and you upload your workouts to Garmin to modify your workouts. I prefer a road run for a faster run however we had a lot of rain last night so the road out front was a mud hole.
