jiffer... Amtrak is a great first century... Cool Breeze only has 3500ft of climbing, but that is still more than Amtrack I believe... and the 3500ft all happens between miles 30-40 in Cool Breeze...
Torrey Pines is only a mile and a half... totally do-able. That's part of my regular ride route thru the whole summer...
I think this will be a great choice! I've not ridden Amtrak Century but HAVE ridden most of the route on my own (72 miles of it anyway) and it's nice! Have a great time...
There is a fine line between "hobby" and "mental illness".
