Hi,
I like the type treatment here and the colors you selected and picked up the abstract runner as well. The race course map wasn't something I noticed so much. I like the idea if you want to play it out a bit more. I've mentioned to a few other designers that we chose the name because of the dual meaning of the word briefs (a summary as well as a pair of shorts) because we think there should be a "fun" element to this. Our audience are amateur racers (triathletes, runner, cyclist, swimmers, etc) who take their sports seriously, but do them because they also enjoy them and find them fun.
Anyway, I hope this helps. Thanks for the creative work!
