Is that the next big goal? good luck!
1:21 half, 2:53 full. Although I get 2 minutes on both starting in the 2018 qualifying window for the 2019 race, since I'll be 35 for the 2019 race. My half PR is 1:23:24, and I've never exactly trained/peaked for a half. That's attainable, I think. So I have several months as a 33-year-old to run the 35-year-old qualifying time :)
