Hampton Half goal 1:26:00

I am a little tired but, no real big issue. I am noticing that my long runs are tough, so need to focus a little more on those. I'd like to get a 1:26 at the Hampton Halfs. I think that is a possibility, but will be tough. All my workouts my legs are a little tired from weight and pushing big gears on the bike. With the casdence work and seeing how I am almost 8lbs lighter from last year, I should improve by a couple minutes.
