What a stud you are to get out and run on that much jet lag. When I go on long flights now I wear compression socks. It makes the ankles a bit more comfortable.
I borrowed some from Hill, and had them on, but they may have been old or the wrong size for me...or maybe it could have been worse.
I discovered a few years ago, on my trips to SWE, that getting out on a run was the best way to feel better, at least for a few hours, after a long, especially eastward, flight.
in 2014, we flew 6 hrs to LA and 14 to Sydney with 30' gate time between. Aboard the big plane for the trans-Pac flt, I made a 50ish yd (rectangle) walk in available space for lower extremity swelling as well as DVT considerations.
I had bilat vein surgery in legs in Newton way back ('76) with subsequent long flights always an exacerbation. Prolonged motionless standing and sitting are the enemy. Running or at least vigorous walking is the best solution for resolving edema.
Running works, it was gone after the run. It would be difficult to get a rectangular walk on the plane, it is pretty much impossible to cross between the aisles.
Back and forth would work, but I thing running would be frowned upon.
We had a pretty long trip home from Auckland on Tuesday-Wednesday. 12 hour flight to Beijing with a 10 hour stopover there. Then another 10 hours to Frankfurt before the final 2 hours to Stockholm. Roughly 24 hours in planes and 12 or so waiting at airports.
At least we made the best of our time in Beijing by walking the full distance of all the arms of the terminal building for a total of 6 km.
Not extremely jet lagged but of course we are tired from the long trip and waking/sleeping hours are a bit off.
Will run an open course at a local event tomorrow to get the body going again.
