Hello Uroš and others,
with friends we were preparing to conquer K24 for the second time this weekend, but the weather forecast is bad. Currently we are still arranging next dates...
On the first K24 we had most trouble in the direction between Pikovo and the hut at Peč and from Kumra to Olševa, where we searched for the right path several times, mainly due to fallen trees, missing markings ...
My route:
https://www.strava.com/activities/2634661572. Not only do you have to walk around 90 km and do 5300 m elevation, your subconscious (psyche) starts chasing you too, especially when you realize you've been awake more than 24h. That's when the real fight with the path and yourself begins. Let me mention you need to take quite some gels with you and energy tablets and hydration drinks. Support along the path is almost necessary, because you can't carry all fluids and food in your backpack all the time. If you're not well conditioned, I advise against the route, if you are, go boldly.
After K24 you'll have walking troubles for 2-3 days (mainly knees will hurt, suggest using vacation), a blister on the sole might burst, ... recommend painkillers and hiking poles (especially for descents). Calculate how many calories you need to eat and when to refuel. Hope you've tested some gels and tablets already.
If anything else interests you, just ask.
Best,
Mihael
P.S.: have you maybe already tackled the route?
