My son is 15 y/o and just started road biking a few weeks ago. Seems he has taken to it like the proverbial fish to water. He rides a minimum of 25 miles per day, yesterday he did 34 at an average speed of 24mph, said he wasn't even tired and could have did more. Mind you, we are in a part of Alabama that is all hills... plus its been in the mid/upper 90s for a few weeks. May not be much for some folks, but I was impressed. What is my next step as a dad who wants to encourage? Sent via Android, UKB 2.0, -100 UV
