This part is what I am trying to estimate.
Your 1 hr is referring to Tower 14 to 20 (that I will add on another 30 min to this). Can you recall the time you took to walk back from Tower 20 to 14?
Also, did you have leg pain the next day? (if leg pain / sore then I would want to arrange the trek on the last two days of my trip else may spoil my whole trip)
*You arrived at around 10 am, what time did you leave?
Unfortunately i don't recall.
But i remember it was quite fast to walk from Tower 20 to 14. Cause downslope.
Didn't take too much photos on the way back.
We actually arrive before 10 (9.37AM?), but it was a distance to walk to the Chairlift / Cable Car. Still need take a shuttle bus (if i remember correctly) to the Chairlift / Cable Car area.
Then we took the chairlift up (around 10:02AM) + take pictures, chill + Toboggan down.
By the time we took the cable car up to Tower 14, it's almost 10:52AM.
Then i reach Tower 20 around 11:47AM. Started heading down around 12:01PM.
(between 12:01pm - 1:44pm = Walk from Tower 20 to 14. Take cable car down. Take shuttle bus. And walk to restaurant)
By 1:44PM, i was already down in a restaurant eating lunch. Finished eating at 2:25PM (based on my receipts). Then walk to wait for my tour bus back to city.
No aches. U can just chill abit and don't climb too fast between Tower 19 and 20.
I challenged myself by going non-stop from Tower 19 all the way up to 20. Didn't pause at all. There are many ppl around me will just sit down on the steps to rest. I didn't, so my legs were wobbly by the time i reach the top of tower 20. But after my lunch it was pretty ok.
My wife is someone who doesn't exercise. She didn't climb the full 19-20, and she had no issues with muscle aches.
