Changi Airport Running
 

Just wanted to share it's totally possible and allowed (and fun, for the first few miles) to run a "loop" at SIN airside. From F60 to E28 (most direct route) to C26 (most direct path) to A16/A20 is around 2.25-2.5 miles. Did this and back twice.

They'll tell you there's no way between T1, T2, and T3 without using the Skytrain (literally 6/6 counters I asked because I read otherwise), but there is airside!

Pretty interesting run too, you see areas that are totally deserted and areas that are completely packed (open areas past immigration, near travelators after arrivals) and some that are completely empty -- and there's a huge temperature variation too. Got a ton of weird looks but no questions or stops by security or airport officials, pretty surprisingly.

No place to leave luggage in any of the lounges, but they have a paid service.

Anyone else do this before? Or is now inspired to?

Not run but walked
 

I have walked that route post TPAC arrival, usually midnight to 1am. I drop bags off at transit hotel, fast walk the "lap" or two.
After that it is shower and sleep; at 7-8am I am awake and ready to go, acclimatized to local time. Ready for SG or onward connections.

I did walk from end T2 to the end T3 and back without rush, took about 50 min.

Guessing that includes travelators? Otherwise seems pretty darn fast!

Yes, with travelators, but I walk quite fast as well.

Without travelators, my brisk walk from transit hotel to T3-T2-back is around 1:15 very brisk walk.
I think at my transit/arrival time a run should not be a problem but it would involve running gear in carry on.

That's cool. Yes, you are right, they are all connected at Airside.

Question is - what do you do with your carry on. The only time I had that exercise was when my flight was delayed and I simply left my carry on at a lounge chair.

If lounges provided lockers, that would be much easier. Last year I crossed MUC twice from back to forth and was surprised that the building is actually 1km long.

Transit hotel. They will hold bag until I finish my walk and then check in to shower and sleep.
However changing into running gear might involve a different procedure of checking into a sleep room.

I changed into running gear in one of the PP lounges with shower, and then left my bag for $4.28 SGD at the airport's Left Luggage service. All of the T2 PP lounges were fairly adamant about not leaving luggage lying around.

So you
- went out from airside to landside
- left bag
- went back to airside
- run
- went landside again
- got bag back
- went airside

If above is correct - too much trouble.

Above is incorrect IME.

There are left luggage service both airside and landslide at Changi.

I have used both, landslide for large pieces, it is cheaper

That's a lot of work for a jog...

I've done the walk couple of times, when waiting for my transit hotel room to be available, but never thought of putting on my jogging gear and running in an airport.

I love running and am intruiged by this idea. But it seems a little odd to run inside the terminal. Why not just use a treadmill at the transit hotel? (assuming it has a gym? It definitely has a pool....so I'd be surprised if no gym)

ISTR seeing stationary bikes I think near transit desk B? Not sure if the other terminals have them too, wasn't really looking, just more of a "hey neat" thing as I was wandering around.
