Did a 25 minute warm up around my house and over a Foothill College as a preamble to a tempo-speed workout.
Ran 2 x 800 in 3:30 ( seven minute pace) with a short rest in between. Pace felt easy.
Then did 4 x 400 in 94-95 with a short rest. Would have run faster but for an issue mentioned below.
Jogged an easy 15 minutes afterward.
Upper left hamstring was tight. It actually felt better as I ran and I took advil and iced right after.
The weather was near perfect 50's but sunny and no wind.
