damn son, 2.5 straight hours of riding is not something I would aspire to do nor suggest attempting. If no money for motels, why not reach out to some of the members on here for a halfway stop? that would REALLY decrease the risk of fatigue-caused accident. Another option is bring a small tent or sleeping bag and sleep at a camp site on the way. There must be something similar near the route. I don't see how you could ride for more than 14-16 hours straight without it becoming extremely dangerous. I'd put you up for the night if I lived anywhere on the way.
there's always a way. Good luck and keep us posted.
Agreed w/ the notion of reaching out to the ZedExCommunity for a place to catch 20 winks.
Berserke81 made some great points regarding lube the chain. I do what he suggest, but I add a twist: I always lube it after I've been riding for a while, and the chain is hot. I use chain wax because it doesn't fling off. The difference that I do is keep the bike running in neutral. The chain will rotate do to inertia from the operating engine. Note: I always stand on the bike's Left side whilst tipping the bike into my thighs. I spray lube on both the outside & inside of the chain.
Others have mentioned the merits of the Camelback. I concur completely, but again w/a twist. H²O alone is not sufficient. When your metabolism is burning lots of fuel you deplete your electrolytes rapidly. These are responsible for neuro-functions. Thus, you become tired/dehydrated. Poor judgment ensues. In short you are dangerous to you and others. I blend a bottle of Gatorade & fruit juice (various V-8 juices) - you choose the flavours. Keep the mouth piece always tucked up in your helmet so you never have to search for it which is a distraction. Also, I do the trick of pouring H²O into my helmet to literally keep my brain cool.
I ALWAYS make up little ziplock bags with jerky in some, dried fruit/nuts in others; and protein bars. As much as possible stay away from candies, donuts, etc. Energy drinks are not long term energies - you get an initial pick-me-up, then get that sugar crash.
Ride smart. If you feel like your brain is fuzzy, and feel disoriented stop immediately, you are suffering from dehydration. You truly are the accident waiting to happen. Your brain needs protein & electrolytes (Na & K). Sounding odd, eat bananas, they are nature's perfect food (high in K). Get a cup of yogurt. Your eating habits on long trips can literally kill you... Or not. So eat often in small amounts, & take in fluids on a constant basis.
Godspeed to you lad, and condolences.
