Walking is a wonderful way to walk off the craves and is good for you 
Glad your sticking with it and recognizing what YOU need to do to protect your quit. Excellent!
Good for you for walking to get beyond the crave, Tinalbowser!! Physical exercise and deep breathing can conquer pretty much every trigger and crave!! Add Chocolate and you're good to go!!
In an early quit, it sometimes (often) happens that the new quitter sees smokers and has the thought "Darnit, they get to smoke and I don't... woe is me!" (I had those thoughts). This is the time to remind yourself... "Smokers don't GET to smoke, they HAVE to smoke"... (and you DON'T) . Eventually, seeing them and smelling them won't bother you in the least, you may feel sorry for them but it will only possibly trigger memories of what you are no longer obligated to do (stand outside in the wind, cold, rain etc. to get a fix).
Keep up the good work, you're doing exactly what you need to do, one step at a time!!
THAT's the idea!
