Improve Cardiovascular Health. The Keuka Outlet Trail, often referred to as simply the Outlet Trail, follows a generally downhill course from Keuka Lake in Penn Yan to the inlet along Seneca Lake in Dresden. This could happen at any time, without warning and could change the character of an event; i. e. take what is planned for a single day event and make it a multi-day event, take what is planned for a mass start race and change it to wave starts, change how our aid stations are set up / aid is provided, etc. The course will be a ~10K loop (on the heavy side) with one aid station near the halfway point, as well as at the start/finish. The trail was pretty and a little technical but not too hard. Water Stops: For races over 5KM there will be a water stop approximately 1/2 way through the course.

Her mind runs alternate scenarios of what might have happened if she'd gone that day, and though she'll never know, she believes he would have killed her. What also stands out from that visit is the enormous engagement photo of her in that wedding dress. Both runs cross the Codorus Creek near the finish. As mentioned above, the varying terrain of trails combined with numerous obstacles forces greater proprioception (a fancy word for perception or awareness of the position and movement of your body in space at any given time) and muscle engagement, specifically stabilizing muscles, such as those in the foot and ankle.
