If your goal really is to finish an Ironman in 15h, the plan should be ok. In 15h you could spend 1,5hrs for the swim, 6hrs for the bike and just hike 42,195km...
If your goal is to actually run the marathon, it maybe would be better to get fitter for another 1-2 years of consistent endurance training (8-10hrs/week should be more then enough) and then prepare for the Ironman with maybe 12hrs/week during a 6 month time frame.
