I utilized the Windows Phone 8 "panorama" page-type. Think of it like one really wide page with different sections that you can swipe between. The first "pane" of the panorama would show live race data.
The second pane in the panorama would show links to specific races, past or future.
Users could set favorite teams, to view their racers, car, and other information about it.
Live news would be scraped from Bing in order to make the app always feel up-to-date.
A section for merch would allow for upselling and location-specific deals.
In addition to a phone app, I also imagined how the experience would translate to a tablet. We could show a lot more live race-data and pivot between different phases of the race.
It all started with whiteboard sketching. Here I laid out the main panorama, trying to figure out what to show on the home panorama, and what the additional page would look like when you drill deeper into the race.
I figured out the order of the panorama and had an idea for a split-screen for the race page where users could drag the split up and down to show more or less information.
