Should be more than enough, I did my Pace RC104 with 3m of it and that has the rear cable routed under the downtube and along the chainstay.
Only tip I'd offer is to get it all planned out in your head exactly before you start cutting and installing barbs/olives because you don't get any spares in the kit.
Oh and for my Formulas not all the bits in the kit fitted correctly so I had to use a few bits off my original hoses, think it was the bolt with the hole in but I can't remember. So don't wreck parts off your old hose getting them off just in case!
