If you saw a woman in a wedding dress going for a jog in Rosalind Park on Thursday night your eyes were not deceiving you.

Catherine Anyon completed her run with friends Brodie Dempster and Meagan Love for the May 50K.

The challenge sees people walk or run a total of 50km throughout the month of May.

Ms Dempster enlisted her two friends in the challenge to raise awareness about MS, which she was diagnosed with back in 2015.

"It (the diagnosis) was incidental, to be honest. I had knocked my head on a window and the doctor sent me for an MRI," she said.

"It came back with lesions and what-not."

MS affected a disproportionately high number of women, according to support group MS Limited. Most were diagnosed between the ages of 20 and 40.

Many people who lived with multiple sclerosis experienced visual problems, balance and coordination issues.

Ms Dempster had kept her good health until a few years ago.

"I woke up one day, just shy of two years ago, and I could not walk any more than a couple of metres without having to sit down," Ms Demptser said.

She had recovered and found that staying active made a huge difference to her health.

Wednesday

DO NOT worry, no loved-ones will be left standing at the altar on Thursday when this bride bolts through Bendigo.

Onlookers may sight Catherine Anyon running through Rosalind Park and other parts of town at about 5pm.

She will be making her dash for charity, not to escape partners like Julia Roberts' character does in the 1999 rom-com Runaway Bride.

Mrs Anyon is already married, but the bridal shop owner raising money for research into multiple sclerosis through the May 50K.

The challenge sees people walk or run a total of 50km throughout the month of May.

Mrs Anyon has pounded 44km of pavement so far.

"I thought it would be a fun way to raise more money," she.

Most wedding dresses are not exactly designed with a two kilometre jog in mind, so the owner of Fifi&Edga Bridal will wear one she is making tonight.

"I have made sure there is a split in it so I can move. And it's stretchy," Mrs Anyon said.

Unlike most brides, she plans to wear runners.

Story continues below social media post.

Mrs Anyon is taking part in the May 50K with two friends, one of whom has MS.

Neither has volunteered to wear a wedding dress when they set out on Thursday night.

They have yet to work out the exact route of their bridal dash.

"It's just sort of about running until the Fitbit says we have done it," she said.

"If it is raining we may have to switch it up to a gym, but hopefully it is not."

The group has raised $1504 so far, including from the sale of veils in Mrs Anyon's shop.

"When I sell a veil, $50 of that is going straight to MS research," she said.
