Great effort and hat's off for giving it a try! I'm an IBA rider and do it routinely on my big bikes. Trying it on a 250 is definitely a challenge.
Just FYI, stimulants are not banned by the rules. Many think it's not useful to count on coffee if/when you get tired. and trust me...at my age I eat ibuprofen during my rides!
BTW....videos here are fine for members to post.
