Here's a fresh take: Brian Walton, an extremely talented rider from BC (that's Canada) had great junior credentials and a pro career that was probably limited by his clean habits and serious allergies. He was a good stage racer and showed mature humor racing with amateurs while on US based GT teams that didn't necessarily share his puritan habits regarding supplements. He was definitely a hero of mine even though he was a bit younger.
He got the silver at 96 track Worlds in the points race which is not an easy thing for a climber physique. His Mom was a Master's worlds champ as well.
His son just broke the Junior hour record and, according to CN's article didn't start riding until 2020 when he suffered from running based injuries. He rode on a velodrome 3 times before his effort in Mexico of over 50 k per hours. There is something to be said for genes and good parents. Congratulation to all of them!
