My friend and I are running this one and will be around the 30min mark too - hopefully!
It's my first race since having my baby 9 weeks ago and it's her first race since a horrible knee injury from skiing so we're not worried about being near the back.
Red Devil 2, I completely agree with you!
Also, just to reassure everyone, coming last isn't always a bad thing. We ran the Amsterdam mara in 2007 not knowing how serious a race that was and there were 2 people behind us out of the thousands who ran it - we had a steel band playing us over the finish line and were greeted with so much support you wouldn't believe it. Honestly, coming last in that race made it all worthwhile so worry not!
