About 50 refunds totaling about $2,600 have been issued to Madison runners, according to Chase Carter, a "Neon Vibe" representative.
"Although we do not state the reason for the move due for business reasons, we apologize several times in the email and offer a $20 voucher," he said.
Carter added the race was moved to Milwaukee due to lack of runners.
"We have been in the business since the beginning of 2013... and never had an unsuccessful event in terms of customer satisfaction," Carter said.

Heather Sonley says she is mad.
"Just be honest and tell me why you moved it, and just offer us a refund immediately."
She's an avid runner, and said what started as a good idea -- the Neon Vibe 5K -- was going to be her first run before marathon season.
"It's a night, you get to go out, you have like an electric party afterward," she explained.
It was a fun run planned for July 12th in Madison.
Heather, along with all the other runners who signed up, paid almost $40 to be a part of it, and it all sounded great until she got an e-mail last Saturday.
"They notified the participants through just e-mail that they canceled the event and moved it to Milwaukee for August 30th," she explained.
Heather tried to get in touch with the organizers for a refund... without any luck.
The event's facebook page shows that Heather isn't the only one; many runners have posted and complained.
Still, no response from Neon Vibe -- they didn't even respond to a inquiry from NBC15.
Now Heather is looking not only for her money back, but also for answers.
"Explain to us why they moved the event, is it because of the attendance, is it because they couldn't get the right permits, we just [want] the truth."
The only thing runners were offered was a $20 voucher to the merchandise booth -- that too, in Milwaukee.
She says one of the most disappointing things about the cancellation is that the run was set out for a good cause -- do donate to the Children's Miracle Network.
Now, not only can she run, but she also can't support a program near and dear to her heart.
As of 8 PM Tuesday evening, Neon Vibe had still not responded to inquiries by NBC15.
