Mrs Legs suggested this morning that (to help her get into shape), we get a treadmill. The obvious place for one would be in the Zwifting Suite, alongside my Tacx Neo and facing the Big Telly. The drawback is that the roof has timber rafter ties only 6'10” above floor level. I don't think it'd be a problem for Mrs Legs, who's 5'3", but I'm 6'3" and I don't want to take my head off if I run in there. Obviously, the ties are the low points and there's 2'8” gaps between each tie - how much back/forth space do you need, and would it be safe to work on the basis of my head bobbing about in this space? Minimum deck height appears to be around 7" but does the panel know of any good treadmills with lower decks? I think I'd want a top motor speed of at least 10mph (6 min/mile).
(BTW, I've considered turning things around so that the treadmill is parallel to the trusses, but I don't think there'd be space.)
