Yeah, maybe 5-6 hours walking per day too little. Didn't think what to do rest of time. You took it easy

Don't know, never been multi-day on foot, so thought not overdo 10 hours day. Though I say I have fitness, still bit afraid how it would be walking 7 days 10 hours day... Anyway would see on go how it goes. As I saw huts every few hours. When reach one see how tired and time and decide on spot sleep there or continue..
Food: thought breakfast in hut, dinner in hut, need snacks in between. Can I buy some along or carry for 7 days? Drinking water in every hut?
Powerbank good idea, and sandals, wouldn't think of that myself.
Should I take sleeping bag too though plan sleep in huts? Reserve huts in advance or arrange on spot? Better mountaineering boots (over ankle) or hiking shoes (under ankle)?
So clothes as little as possible and something for rain, right? And maps. Are there maps in Slovenian Mountain Trail guide?
