The sisters have been training on their own for this race along with the online support of their respective training coach, fundraising coach, and fellow Teams In Training (TIT) team mates. Alicia's Flex team, which is made up of runners from Maine, Massachusetts and New Hampshire, is feverishly working to raise $2,900 each for the Leukemia and Lymphoma Society, the nonprofit that receives all the proceeds from the Rock 'n' Roll half marathon in California.

"This is probably one of the coolest programs I've ever been involved with," Alicia said.

"My team is halfway to its team goal of $210,000. You all train on your own, but we get emails and know each other exists and we all want to see each other succeed."

However, outside of the actual race and her sibling rivalry with Ashely, Alicia admits she is also in competition with herself.

"I'd like to personally raise $4,000. There's never been a top fundraiser from Maine on the Leukemia and Lymphoma Society Team In Training list that is put out, and I'm determined to get on it."

She would also like to improve her speed. Alicia's personal half marathon best is 2 hours and 32 minutes, which she'd like to shave down to 2 hours and 15 minutes, a challenge she is ready to face considering there are a few hills along this year's 13.1 mile Rock 'n' Roll race route.

"Hills are terrible," Alicia explained, who is trying to remain positive and focused on the finish line, despite her sister's best efforts.

"My sister talks a big game. But so far I'm ahead of her," Alicia said. "But I am afraid she could beat me."

The San Diego Rock 'n' Roll half marathon will take place on June 3. If you'd like to support Alicia, log onto pages.teamintraining.org/ma/rnr12/AlyC to make a donation or email her at  This e-mail address is being protected from spambots. You need JavaScript enabled to view it .
