WU is key. CD not as important, but if you have done a fast 10 miles it’s recommended. Also if going for a quick one including drills and strides (4 bonus pts) is worth while too.
Knowing your goal pace beforehand is important and ensuring you don’t go off too quick is crucial. Obviously that will be determined by the elevation of the route. But I’m always happy to discuss pacing strategies and race tactics beforehand.
Good Luck!! You got this 💪
