Interesting topic. I find the same, when the weather is good like now, I'm pretty reluctant to train so I'm fresh for rock climbing. But I definitely feel strength and strength endurance slipping away. My plan is to get in at least one fingerboard sesh per week, maybe after a climbing session if necesary. A few max hangs and then some repeaters has always served me well. Then when we get a spell of bad weather, bound to happen sooner or later, train like hell. Intensity of fingerboard sessions will be judged by the forecast. If i'll be climbing the day after tomorrow, keep it fairly light. I'm not bothering with any endurance stuff, as I figure I'll get that from climbing. Also doing the odd session of laps on sport routes when out might help.
Personally I wouldn't bother with the running etc (unless it's just because you like it). The theraband and TRX stuff shouldn't affect your recovery for rock climbing enough to be missing it out, it's just time I suppose
