Who Builds Kracey
Hi, I am Niels Post, and I build Kracey. I am a former national swim athlete and competitive rower who qualified for the Ironman 70.3 World Championships, then moved to HYROX and finished tenth at the HYROX Pro Doubles World Championships.
For years I coached myself. Rebuilding old Ironman blocks into HYROX and running plans, copy-pasting everything into spreadsheets and pushing it into my calendar by hand. It worked, eventually. It also ate every evening, and I still could not tell you on a Tuesday whether Thursday should be hard.
So I built the coach I actually wanted: one that reads my data every day, holds the plan, remembers the context and tells me when I am about to make a bad call. The framework behind it comes from a year of being coached by working coaches and by an elite Pro athlete. I train and race on it, and it argues with me.
I write the blog as well. The four nutrition-led posts are reviewed by Emma Carter, a Certified Holistic Nutritionist.
