Ok so the overpassed are the challenge. When you say they are long is that a quarter mile or worse? Sorry. I just have hill phobia and surprise ones are worse! Thank you!!! Also maybe need to ask elsewhere but is navigating the starting area self-explanatory? Have only done local races. Largest had 1000 people I think. We have race retreat set up. I just feel overwhelmed with all the info and really nervous about messing it up! I had a dream I missed my corral starting because I was buying ice cream!
