I am getting near 60 Cliff, similar to you in age. My youngest is in his last year of high school come next semester. I keep myself fit. He and I started riding our road bikes several years but volleyball took my training partner away for a couple years. He's been running, jumping like a monkey, lifting weights during the entire summer with his team. When time allows and if he's not too tired and busy with friends, we still go out and get 20 -30 miles of riding in. Im in great riding shape so I stick it to him at about the 20 mile out and he's drained but damn, nothing beats youth. On our way back home, its a one mile long hill with sections of it at 12-14%. He knows where to jump me and I have to play catch up with my experience but that only go so far. They have a lot of energy and recover time are measured in seconds not minutes. We just need to keep ourselves moving and stay somewhat fit. My resting heart rate is in the low -mid 50s
Enjoy them. When they want to hang out and do stuff with you, this tells me you are a fun and cool dude. Most kids don't want to have anything to do with an adult. Just make sure you give the baby sitting bill to their parents
