Ms Davies, who used to train at Bracknell Leisure Centre, carried the flame through Leominster in Herefordshire in May and is encouraging everyone to line the route in Bracknell to cheer on the torchbearers.
The three-time Olympic swimmer, who lived in Crowthorne in the 80s and early 90s, said: "It's incredible. I hope everybody comes out onto the street.
"I think this is going to be a great way that people who can't get hold of tickets or go to London can still feel part of the Games."
Ms Davies, speaking to the News before she presented student awards at Bracknell and Wokingham College on Monday last week, added: "I just hope the sun shines for you!"
Nine torchbearers will carry the flame through Bracknell, but only two are from the town.
One of them is lawyer Sharon Barton, 34, from Whitegrove, who said: "I'm feeling really excited and a bit nervous!"
The other local torchbearer, Richard March, 31, from Birch Hill, added: "As it gets nearer and nearer, people are talking about it more and asking me about it. I can't wait - it's going to be a great day."
Torchbearers Andy Jackson, from Wildridings, plans to make his torch a beacon of hope for Bracknell by using it to raise money for a debt advice charity.
Mr Jackson, who set up the Bracknell branch of Christians Against Poverty (Cap) in 2010, hopes to raise £8,000 for the organisation by asking people to give a donation to be photographed with the torch. He chose the target because 8,000 is the number of torchbearers and the number of holes in the gold-effect torch.
Mr Jackson, 48, who oversees social justice projects including Cap at Kerith Community Church in Church Road, Bracknell, said: "One of the reasons I was nominated to be a torchbearer was around setting up the debt centre with Cap, the national charity, so I thought it would be nice to complete the circle in a way. It is something close to my heart."
He will carry the torch through Maidenhead today (Tuesday).
Businesses along the torch route in Bracknell are preparing to celebrate, and both The Running Horse pub and The Royal Oak are putting up bunting and expect a large number of customers keen for a good view.
IT company Maximiser Software, based at Apex House in London Road, is inviting children from Holly Spring Infant and Junior Schools in Bullbrook and their parents to watch the relay from its offices. Managing director Mike Richardson said: "We thought we could add to the excitement and give them some refreshments and something to wave, and make it more of an occasion for them. Hopefully it will be good fun."
