I run and occasionally do sprint tris. I carry a phone for both riding and running as I use Strava to track and compete with others. The thing I'm excited about is that this watch has a HR monitor, which is what I would need as you train based on intensity. Not to mention when you're stranded 50 miles due to a flat tire, you'll need that phone to call for a pickup. Others have mentioned listening to music,..etc. (I don't) Look - you're going to carry a phone everywhere you go on land.
