Let me preface this with the fact I am not taking this very seriously, I'd like to get a decent enough time not win it. I'm 25, 6'2" and in pretty good shape. I plan to do a Tri in July for fun and am going to take it in consideration when I buy a bike that is for trail riding mostly.

I'm looking into DS bikes as I only have room to have a single bike in my life. Please don't get me to buy more than one bike. I love riding long rides on road and trails that can get pretty rough so front suspension is a must for me so that almost pushes me to a DS bike. I'd get one with a lockout though. I've looked at Diamondback Trace bikes and Trek DS so far but am open to other bikes around $1k or below. I also plan to ride on the road quite often so I'll probably have 2 sets of wheels, one for trails and one for road.

What thoughts do you have as to brands and models that may fit my needs? I've read the guides on this section but they are more for setting up a bike for tri and not trying to get a good balanced bike.
