very Stupid Idea , oh yes

my first ever sprint Triathlon is now nearly 3 Weeks in the Past, however there is not a single Day where I don't think about Triathlons. I'm not even sure I enjoyed my first Try on a Tri that much, however I can't get Triathlon, Triathlon Training , Triathlon Distances out of my head and the most Stupid thing I can't get out of my Head is :  IRONMAN 70.3  

Something is telling me I should take up that Challenge , which would exist out of : 1.2 mi. swim • 56 mi. bike • 13.1 mi. run ( that is in Kilometers: 1.9 km Swim, 90 km Cycle and lastly a half Marathon of 21 km ) .

Ireland had two Weeks ago it's first Ironman 70 event and I expect it to be back next Year in September , so  I would have 1 Year to train for this and if I go with it, I will need every single Day of this Year to survive that .
I haven't even done my first Half Marathon yet and I know I will have problems to finish that Race, so even thinking about that Ironman Challenge seems to be extremely Stupid, but as I said I can't get it out o my Head.
If I take it on, it will mean the biggest Commitment I have done , it will mean quite a few expenses and it might mean to do a really horrible Race in a Years Time .
So why the Heck is it bugging me so badly , I guess several Reasons , firstly nearly every Challenge I did set myself this Year I have conquered and done .
I did : a 33km Night Hike , which was a extremely though Hike in the Wicklow mountains, I fell in more Bog holes than anyone else, my Feet were soaked through , for some reason I couldn't eat during the Night but I did finish it .
 I did nearly every month a 10km Race ( Doesn't sound much but it is big for me ) , I did my first ever Triathlon and lastly I lost a huge amount of Weight.
I haven't been so healthy in Years and I know I have to keep this Body Fit and see how far my Lungs can take me .
So setting myself though Challenges  and conquering them, seems to keep my Heath up , it makes me proud of myself and it is very satisfying.
 So I have been thinking what should  I do next Year , a Marathon ? Sounds a bit Boring just to do running , an Adventure Race , yes absolutely and if possible I want to do one next Year, but for some Reason it doesn't sound so appealing like the Ironman 70  .
 Things I want to do next Year again are the Night Hike , certain Trail Runs etc but I need something special, which would be IRONMAN 70 , just not sure if I'm though enough to do one , but  I guess the only Way I ever will find out is to Try an Ironman.
I give myself another couple of Weeks to figure it out , in that Time I can start to look into Trainings Plans and books etc, because even if  I don't do the big one I defiantly do the Smaller ones Olympic Distance and sprint Distance
