In checking the site am I understanding that the 1/2 marathon is 10 miles???? Also I noticed that if you cannot keep at least a 16 minute mile they carry you to the finnish line... So I guess if you are not a runner as long as you can keep that pace you can power walk? Or is it for runners only? I may be there for moral support but we will see.... BTW DOC what is your time for 1 mile? If you don't mind me asking
