Took a new path today

My son wanted to try a different route so we turned left out the driveway instead of right today and there were far more hills in that direction. I've mostly been doing two straight paths on flat surface with maybe a slight but hardly noticeable incline. Not today though. This time it was one straight shot down and back but some decent sized inclines. He enjoyed just coasting down them but I made sure to pedal my feet even on the downhill parts. My heart was definitely racing by the time it was all said and done.
