Do you do destination races?
Yes, I have done 2 official destination races and have 2 more (Oct & Nov) this year. I've done one out-of-town race, but I don't think that necessarily counts as "destination".
Where have you been?
St. Pete (Women's Half) & Chicago (RnR)
What is some advice you can give newbies?
I found packing my race day breakfast (or buying it as soon as you arrive at the destination) is the best choice to avoid stressing - I've not found any eateries open early enough on race morning. A bagel, peanut butter packet, and knife come with me for every race.
