50 miles/day sounds aggressive to me - I'd think about 30/day might be more reasonable for kids, especially if they have not been routinely training by biking a few times a week for at least a few months. On long rides, you cross a line where it stops being fun and becomes a grind; most kids would probably cross that line well before 50 miles. Also, consider having other parents/leaders meeting you at trailheads along the way, as "sag wagons" for the kids who run out of steam. Regardless of what you decide, I hope you and the boys have fun.
