As part of the Boulder Racing Series, every summer they hold one of the races in Niwot. The course is a one mile figure-8, and it's perfect for photography since the riders lap it every 2-3 minutes. The level of racing is ridiculous- pros from Colorado can definitely hold their own among everyone in the US, let alone the rest of the world. I hopped on my cruiser and rode a few blocks to downtown and took some pictures this afternoon.
