Mandatory Drug testing?

So last post I mentioned I signed up not for the 1/2 marathon as planned for in October but the full marathon. Now some background. I'm fairly new back to running and most who I've talked to about this think it is nuts and wonder if I might have been consuming some non performance enhancing non prescription, non legal medication during the sign up process.  I'm still not convinced either way. I need some input from anyone who might have experience.  Here is my rational for the full not the half and a bit of background on me beyond what the rest of this blog explains. I have always thought of the marathon as a great fitness goal, a challenging achievement (the half most certainly is as well but isn't in my mind as out there or as motivating).  I have no time goal just to finish and I plan to continue training and doing the event using a run walk method, kind of a Jeff Galloway thing, google it if you aren't familiar.  I'm able to comfortably run over an hour and over 6 miles at this point and have been walking and then running since September though running is really since Jan in any consistent way. Finally if I get up in mileage later in the summer during the long runs and find it too taxing on the joints etc then I'm happy to shift into the half and run a full at some other point. Right now I have momentum and motivation and summer gives me the time to put in the miles. Happy to hear your thoughts! 

Going great and and October challenge is decided.

In last few weeks things have really come together. I've been exercising with intensity and duration (at least an hour for the past 18 days. Eating is becoming pretty focused and I'm making good choices not feeling deprived. No back pain except when swimming so I've backed off that for the time being and increased the focus on tennis, running, biking, core work and the hundred push up program. Onto week 4 of the 100 push up program this week, just finished my first "long run" about 10k, I know not a long run for those who "run" but we are building up slowly, and had a couple of longer rides this weekend. Still filling out some of the 12 monthly challenges I'll set for the 45th year but October is now decided. 146 days from this post I'll be in the midst of my first marathon. http://www.hly royalvictoriamarathon.com/ On 10/10/10 the world will not end but I will hopefully be able to tick a box on my really want to do life list. I went to early register for the half Marathon but this is a year of pushing, a year of the highest level of fitness possible so 42.195 km or 26.2 miles it is. I'm pretty excited and have no time goals it is to finish and be able to enjoy celebrating after the event. We shall see.
