This is a rooftop race in the Los Muertos territory that you end up running for awhile and returning to your base. There's a checkpoint in the water about mid-way into the race, and I can't seem to get it. I tried jumping into it, swiming into it, I'm lost.

So how did you guys do it?

There is no checkpoint in the water, I have done this race. I have never gone into the water.

Ugh I suck. It's in the tunnel, isn't it?

I was on the water ABOVE the tunnel this whole time.

Yeah in the tunnel.

heh, that ones a b*tch
be careful of timing out while climbing the agency tower. also for the run to the tunnel you can get in a car and drive through the points.

I found this one quite easy. Once you're running on the road, get a car and just drive to The Keep. then just jump up and get the rest of the checkpoints on the building.

Yeah, it was simple. It was that checkpoint that's inside the tunnel going to the keep that kills me. If you swim in the water above the tunnel you can see the green beam of light which is actually the marker in the tunnel, so I kept trying to go for it in the water. I didn't even bother going into the tunnel because I kept thinking, 'It's a rooftop race, there would be no reason for me to go into this tunnel." Well, I was wrong.

Woo to completing all rooftop races.
