Meggan Dawson-Farrell (20) has won £2000 plus a share of £100,000 thanks to Kumho Tyres' Cash for Causes.
The funding will help cover the costs of training and specialist wheelchair racing equipment to net her place in the 2014 Commonwealth Games Scotland Squad.
The Forth Valley College student won the regional vote which took place at SMS Alloa Ltd, and managed to tie the voting with Friends of Bude Sea Pool for the national prize - decided by online votes at www.kumhocauses.com.
Originally, the winner of the Cash for Causes online vote was to receive a national grand prize of £2,000 with the runner up receiving £1,000.
However, in light of both Meggan and Bude tying for first place, it was decided Kumho Tyres would top up the prize fund, awarding both parties £2,000 in recognition of the fact they are such worthy winners.
"I want to say a very big thank-you to everyone who voted for me online in the Kumho Tyres 'Cash for Good Causes' poll," said Meggan, who is with Red Star Athletics Club, based in Glasgow.
"It was great to get so much support and thanks, also, to scottishathletics for getting involved on Facebook and Twitter and asking people to vote.
"Kumho have said we will each receive £1500 and that will help towards competition costs in the coming months. I am delighted."
She added, "I'm amazed that I've secured joint first place. It just goes to show you what the power of a small community can do. The funding is vital to my ever increasing training, equipment costs. I'd like to thank all that voted and especially SMS for putting me forward in the first place."
The international company pledged to make a difference in local communities over the summer by donating money to deserving causes.
Andrew Stuart, manager at SMS Alloa Ltd, said, "We nominated Meggan because we think she's amazing.
"Despite having a disability, she doesn't let it get in her way; she has so much get-up-and-go it's just inspiring."
"The news Meggan tied for first place in the Cash for Causes campaign is fantastic. I'd like to thank our local community and everyone else who voted for Meggan across the UK for their support.
She has the qualifiers for the 2014 Commonwealth Games coming up soon, so this money has certainly came at the right time to help with her training costs."
