For a few years I have got on fine with my saddle height. Slight soreness on rides over a 1000km but nothing a liberal application of Sudacream did not help with.
In Feb I moved my audax bike's seat post over to an MTB temporarily as I was building a new bike and it fitted. Moving it back I did not notice the saddle was ~9cm higher than my commuter (same size frame & crank arms). I rode a DIY 600 with a set of tri bars and made good use of them. No I'll results all round (heatstroke excepted).
Then later that month I rode a hilly 300 and the result was injured right Achilles. Months off the bike, I thought I'd sorted it out, but a 400 proved my wrong in both Achilles.
Googling I found seat height to be the problem. A left over piece of tape marking the wrong (MTB) seat height was the culprit.
I proved this a week ago on a 200 with no I'll affects.
So my question is, what do riders do on long rides, 500km+ if you use tribars, what do you do with your seat height. Or am I looking at the wrong bit, do you use longer stems, or somehow push your tribars forward??
Cheers.

Using aerobars (or drops) is likely to put more strain on your achilles than riding on the hoods / tops as you are putting more of a stretch down the back of your body.
I have had achilles pains after a few days on long rides (TCR, IndyPac) and have got relief by dropping my saddle a bit.
For a pure TT bike you might go for a longer stem and / or shunt your seat forward, but that wouldn't work for a multi-day ride; you'd have too much weight on your hands and shoulders. It's actually more common amongst ultra-riders to fit a shorter stem when adding aerobars.

When you say '~9cm higher', that's a big difference. My saddle heights are all very carefully set up within millimetres. If I get a saddle too high it's a hamstring that complains first - I have a lot of flexibility in the achilles area as years ago I read about 'ankling' (https://roadcyclinguk.com/how-to/technique/improve-pedalling-efficiency.html) and have been a dedicated ankler ever since. I have never used tri-bars tho' as I am quite happy on the drops.

of course there is an expensive gadget solution

In my case I have quite high handlebars with shallow drops, and "comfort" tri bars. Seems to work fine as a package. See https://audaxing.wordpress.com/2017/04/23/tri-bar-setup/
