I'm also curious, is it recommended to use more cushioning for the 70.3 or just use your light weight racing flats with no/little support?
Probably something you will build up to. I used to race in Noosas, bit heavy though. Switched to racing flats (hyperspeeds), but initially could only do sprints in them. Then OD and this year I ran my first 70.3 in them sans socks with no problems. I'll probably wear them for a marathon in July, see how I go, if all good then will use them for a full at the end of the year. Not sure what plan B will be though as I don't have an inbetween shoe. Long training shoes are done in Hoka Cliftons and I don't want to race in them. But I think I should be OK.
When I first ran in them, I planned to do a light 10km, got to the turn around point and had to hobble home. Calves were so sore and I had 3 weeks of DOMS at the end of which I tore a calf which I'm guessing was connected to the original run in them. I love running in them now though, no soreness, feel quicker and they seem to promote a bit more of a forefoot stroke and overall better technique, at least that's what it feels like. The Noosas are 280gms and the Hyperspeeds 180gms so you do feel the difference. But I reckon if you're prone to injury, DOMS etc then either stay away from racing flats or buy some and just wear them for shorter stuff to start with.
