Half "walk" marathon AFTER the Camino

So....to keep myself motivated to keep walking now my Camino is over I just signed up for a half "walk" marathon. I just HAVE TO do something until I can do another Camino in the spring of 2017 again.
It's just strange...here I was walking days in a row half marathons (and more) with a pack and up and down hills and that was no problem....and now my mind plays tricks on me ....."ooooh a half marathon...that's a lot" ha ha ha .
Anyway...I hope it will help with my post Camino withdrawal issues

I know ha ha and I will go again for sure in 2017......I'm even looking ino maybe just 2 weeks in 2016....but am not sure if I should....will that be a let down ???? Or fu to do 2 weeks to get a taste again and to "bridge" the wait till 2017 ????
My Camino was in my eyes perfect......due to the fact my 20 year old son walked with me. He may join me again in 2017 but not before. So I'm trying to hang in and be patient...but omg I soooooo want to go again asap
