It's early, but Northern Plains Athletics is officially hosting online race registration for Bikecicle 2015. If you're in the Grand Forks/East Grand Forks area in February, you should check it out.
Some details and history: Although this is a first for NPA, I've been running online event registration for two organizations since January of 2013: ENDracing and Ground Up Adventures (including GUP subdivisions Northern Heights Rock Gym and Boathouse on the Red). This isn't necessarily to brag or even try to sell you on using NPA for online registration--just to reassure you that I know what I'm doing. That being said, these are all in addition to a "regular" job--and so handling (many) additional race registrations at this time would detract from the quality of service I'm able to provide.
I'm providing online registration for Bikecicle as a way to help out the Northern Star Cycling Club, and because I think some of the other online registrations end up charging more than small events want to handle. Doing this as a hobby, I don't have to worry about overhead as much, so I can charge a little less.
