The organizations are committing to a $25,000 sponsorship.
Highmark and Saint Vincent officials said they are excited to be a part of this fitness challenge, as it is a way to promote healthy lifestyles and a way to support the Barber National Institute.
The Barber Beast on the Bay takes place on September 6th.
New this year to the challenge are a brand new ten mile course, an elite wave for serious competitors, 16 and 17 year olds can now take part, and there will be "cheering zones" to keep people motivated as they try to "beat the beast."
If you sign up before the month ends, you will receive 35% off the entry fee.
