this, too. distance is the integral of velocity, so it benefits the most to get up to speed asap over the top of the hill and into the downhill before letting off any power to recover. I also find it beneficial to start my climbing effort in the nadir of the downhill, bringing as much velocity into the face of the hill as possible. I try to carry that speed into the face of the climb as long as I'm able without going anaerobic. I aim to pedal 110-120rpm into the climb and let the grade push cadence down to 90 and then use gears to keep it there.
