CCN now has an API that allows you to grab real time data on how much money all of your donation campaigns have generated. You can display this total on your event website.
Here's all you need to do:
GET https://2mev.com/rest/v2/events/[event slug]/fundraising_total/
What's my event slug? It's the end of the URL for your registration page: https://ccnbikes.com/#!/events/bc-triathlon-2018
