I was the runner up in the Dallas Half last year and didn't have a great experience at all.
1. I was given the wrong colored Bib.
For some reason i was given a marathon colored bib instead of the half marathon color, Even though at packet pick up i got my bib at the half marathon area.
2. Elite Bibs are impossible to get, the race director never emails you back
3. When I was finishing (.25 miles from finish) the Cyclist I was following made opened a gate along with other officials and told me to switch sides of the road. I didn't know why until I was finishing. It was because they saw my marathon colored Bib and thought I was in the marathon ( i ran 1:08:56).. Which would be a descent marathon time i must say. As i finished the race announcer kept saying "Oh i dont know how he got on that side of the course" and "thats not right, well have to try to figure this out" and other things basically eluding that i had cut the course or something It was quite an embarrassing experience and I had not done anything wrong.
4. They tried to DQ me
After i finished, a race official came to me and said since i had a marathon Bib on I would not count in the results for the half marathon. I told them that doesn't make sense because the marathon is more expensive than the half and i paid the price for the half, the officials still said i might not count but would see what they could do.
All in all they got me in the results, which at that point i could have cared less. It wasn't a great experience and I love the Dallas Marathon/WR and hope things get better.
