24-105 will cover the walk around. Not sure how close to the band but with a crop sensor it should be plenty long as you seem mobile. Then an ultrawide for those cool shots of the bikes up close and personal. I do not see much call for a long lens as you seem from your description you have close access to the events and displays. A long lens would be a lot to carry and be pretty worthless for 95% or more of the shots.
