Recently I mentally added Jon Climber to that list too. Though he was always a legend in my eyes, but a recent message made me realise how far out the box he actually thinks/looks.
I could say, Mike Hall aswell who may have kicked off my love/desire to ride farther... Is that more than three

1. Wildcat Gear, Beth, Ian B and Bearbones Bikepacking (think it was Ian that led me to BB forum)
2. Mike Hall, Transcontinental Race (before I actually knew he was the course record holder for the TD thingy) and without a doubt the chap he was racing during the Australian Race - so humble, both of em and the interview Mike had done of him [forgotten his name, but it's my lovely dyslexia] was so fantastic and down to earth. Still can't find it since his sad death...
3. Karl and 'The Others' (including Gian).
