I've had similar, but not with skydiving. I've only done one dive, and it was pleasant, lovely view, but did absolutely nothing for me in terms of adrenaline, at all. What did work for me was commuting by cycle in London, flat out race with everything for 10km. Legs burning, drop the temperature, maybe some snow in the eyes, bring on the elements. Great stuff. Winter is great for that, cold at first, but ride hard, warm up, and get to work without needing a shower.

I love cycling in London, because it teaches me not to be shy.

But once that lesson is learned -- there's not much need for adrenaline. Just rational aggression.

Teaches you to look in the eye of the guy in the car behind you at the lights to make sure they've noticed you :)

I don't (think) I'm doing it for the adrenaline, that would have faded sometime in the last 10 years.

Besides, as you said, you can get that cheaper/faster by riding a bicycle in rush hour traffic or standing near a ledge.

I think it's the 100% focus that does it, which sounds similar to what you describe with racing mode.

Cycling the streets of London, yes! I loved that. Did a Putney to Canary Wharf commute for about 6 years. Weaving in between traffic that's stuck fast is wonderful.

Even when I got a soaking it didn't really matter, you get so wet you can't get much wetter and then get home and have a warm shower.

It was also a great way of getting rid of tension. If you're angry you pedal harder and go faster which is more fun, so breaks any vicious cycle.
