Dylan, thanks for the great content. What I do not comprehend is that a rider of your level, makes the mistake that pretty much all riders make and goes out at 300w in a race of this length. I do not know how this relates to your weight, but a race this long cannot be done at threshold, just because you are used to racing in this zone! Where are your heart rates in the climb? With a little more race planning you can do top 10* and it will not require drop bars even.
