Switchback Run


Probably the toughest 5K you have ever attempted and you’ll have a hard time seeing straight when you’re done. Roughly 4 loops of what locals call – The Switchbacks. Dirt, rocks, uphill, poor footing predominately on beautiful, memorable trails. The loops cover a section of the Waterloo trail system. Full details and registration flyer can be found HERE.

Asics DS-Trainer 21


From daily training to tempo runs, the Asics DS-Trainer 21 is a versatile option that combines an ideal balance of speed and support. Rearfoot and Forefoot Gel Cushioning Systems work with a Solyte midsole to deliver lightweight cushioning, while a dynamic duomax system provides just enough support for mild overpronators. Along with a seamless upper and heel clutching system, the DS Trainer provides a secure wrap when paces increase.

Overall Thoughts

The DS-Trainer 21 is a great option for runners who need a little support while they are running faster paced runs. The heel to toe transition is quick and great for those faster runs. The shoe is also a safe racing flat option for less experienced runners who have not worn racing flats in the past. If you are looking to add another shoe into your rotation of shoes give the DS-Trainer a try the next time you are in.
