The Hot Chocolate 5k and 15k are run all over the country and because of that the organization, volunteers, and support are top notch! This race also has AMAZING SWAG! Race bib, embroidered zipper sweatshirt, nice drawstring bag, sweets along the course, and an awesome finisher's food (mug with dipping chocolates, an assortment of dippable snacks, a banana, and hot chocolate).
The expo is great with many amazing expo vendors like Nuun, Runner's Roost, 2XU, and others. Lots of official merchandise too!
This race is pretty flat and a nice tour of the city. Part downtown, part warehouse, and part residential as the course winds through Denver, CO. This is a great course for setting PRs and also for first time runner looking for a friendly environment. There are also "sweet stops" along the way handing out marshmallows and tootsie rolls.
All around this is a great race and I highly recommend it to anyone looking for their next race!
