On Saturday I had one of my last solo workouts before joining back up with The Triathlon Squad in Poway. I did some short hill repeats at Challenger Park in Simi Valley. I grew up running there as a kid and continued to practice and race there in high school. Some of the trails at Challenger are still some of my favorites to run to this day.
My dad made a video of the workout and posted in on Youtube. If you have a few minutes, check it out. (at 5:30 into the video I explain the workout and say a few things about running at Challenger Park)
