These are things I do remember that it is all my opinion and everyone has there own advice but you guys can have fun adding your own two cents:
I start out with a good heavy dinner and a good heavy Breakfast as well. I really like to have 9 grain cereal some eggs toast. Some try super hydrating, don't like doing this in the morning but you have you options.
For the Start: 1 bag of trail mix apple and gu flask 1 bottle of water. Yes I only take water to Preston I have seen and heard of guys so loaded up with electrolytes they can't stomach them at Preston and end up bonking. I also carry a two co2 cartriges in my bag with one tube and a box tube in my jersery. One year I had two flats in between stops and on my second a voluteer was there within 5 minutes to help. But because of the second flat I missed Josh and Matt in Afton so your choice. I also have a bag of meds and electrolyte tabs with tums, same thing I have had on the other rides
Preston FZ1: 1 h20; 1 Endurox; 1 12 oz gatorade (I down this and drop in the drop zone) here I pick-up Bars licorice and have different flavoride gu's. I usually take two Bars and some licorice here.
FZ2: Nuetral have to get off your bike to get anything usually pass.
Montpelier FZ3: turkey Wraps did this last year and loved it. I rolled them up and cut them with a toothpick so I could eat it quickly. I stop for a short (under 5) here I just don't do that good stoping and starting much better and recoverying on my bike by going a slow pace. I also pick up a new h20 and electrolyte tab and down another 12 oz bottle of gatorade and a banana and or oranges
FZ4: Nuetral have to get off you bike to get anything, depends on the weather some time this good to fill up on water to get ready for the KOM (king of the Mtn) race.
Afton FZ5: Same as Montpelier
Alpine FZ6: New H20 and Electrolytes, switch bars,
Hoback FZ7: This I usually have to stop and take my shoes off and walk around. Refill
Finish line: Absolutely make sure whoever your support is to bring shoes!! and new water!
walking back to the car in bear feet or in you cyling shoes is not fun.
Hope that helps.
On the meds I did not take any last year and felt great but I always take them just in case.
Also I have a bag ready if in looks like snow in the canyon to switch in Preston as well.
Lets hear others pionts of view LOTOJA Vets!!!
