Supersapiens have been throwing these at Ironman entrants in the UK this year. I’ve only raced a couple of 70.3’s & yet seem to have acquired a stash of about 10 SS sensors for nothing.
I tried wearing a couple for both low & high intensity and volume training weeks, but as people have said above, the main thing I learned was that I’m not diabetic.
My wife is a GP and she was equally unimpressed. We’ve still got 6 or 7 unused sensors in a drawer which I doubt we’ll bother trying…
