I had no idea what a big race this was. As a short race I was aiming for speed and the crowds were challenging to navigate. With 20K+ runners they maybe should consider a more corralled start.

Also the course was horrible. We ran half of the race underneath Wacker which made my GPS watch totally useless, and I was relying on that to keep my speed up! Please consider a new course. Also the shirts are also useless. Mine is a bag and will be getting donated.
