I am considering doing an unsupported 320km race that begins at 11pm and will take approx. 13 hours. It is an A-B race so no laps of any kind and leaving supplies out is not allowed.
Practically, with the lack of opportunity to buy food on the way (the first 8 hours will be remote and at night) this means that I will need to take much, if not all of my nutrituion with me from the start. This approach also allows me to focus on the effort rather than the logistics of food but clearly has a weight/space penalty. I should also mention that there is relatively regular access to water so I have no need to carry more than 2.5l at any one time (2 x 750ml bottles and a 1.5l bladder).
My fuelling plan is to have 1 x SIS gel, 1 x Clif Shot and 750ml of SIS Go every hour. This equates to 100g of carbs/hour for 13 hours.
To achieve this I would need to carry 13 gels, 13 shots and 52 scoops(!) of powder!. The gels and shots are managable in terms of size and weight (a total of 1kg) but I am struggling with the powder - 52 scoops will take up a fair amount of space and practically speaking will not be that convienient.
Has anyone dealt with this issue before? I was thinking of making up a concentrate of the powder which might help on the space front and on the convienience front - I could squirt the concentrate into my bottles and bladder rather than scooping powder. But unsure how much water is required to make 52 scoops of powder sufficiently viscous to squirt and this additional water is clearly additional weight.
Thought I’d share my problem and see if anyone has any clever ideas out there.
