It didn't matter that Mr Bell had never actually met Mr Calder.

He stumbled on Mr Calder's story on the Facebook page of WDEA, an employment service for people with a disability.

An employment consultant at the Maryborough WDEA branch, Mr Calder was diagnosed with multiple sclerosis aged just 23.

Now 37 his health has begun to noticeably go downhill in the past year or so.

Once he could walk 100 metres easily but he now struggles with 20.

"In the last year my walking has deteriorated," Mr Calder said.

But a potentially lifesaving treatment could save Mr Calder. Called hematopoietic stem cell transplantation it could essentially reboot Mr Calder's system, leaving him free from MS.

Stem cells will be taken out of his bone marrow to be stored and farmed.

Mr Calder will then be hit with chemotherapy to completely clear out his immune system.

It will kill any bacteria and germs, including the cells in his immune system which mistakenly attack the fatty acids surrounding nerve cells.

His bone marrow will then be re-transplanted.

Mr Calder has been told the treatment has a success rate of between 75 and 90 percent.

The problem? The trial is in such early stages in Australia that there's no way Mr Calder would be eligible.

It is available in Russia, but both the treatment and travel are costly, all up about $100,000. So he started a Go Fund Me Page.

It was this that caught Mr Bell's eye.

Mr Bell thinks it was sympathy for Mr Calder's four year old daughter Kenzie that made him decide to help out.

"I think that's what made me want to do it, because I didn't want to see Don's young girl grow up not being able to pass the ball [with her Dad]," Mr Bell said.

To raise funds Mr Bell will compete in a treadmill challenge against WDEA. They'll set up a pair of treadmills and go head to head walking or running 50 kilometres.

The team from WDEA will take turns on their treadmill, but Mr Bell will go it alone.

The steps will add to the scores of kilometres Mr Bell has already totted up running to raise funds for others.

Since 2016 he's run in "two handfuls" of fundraisers.

Mr Bell said he just hates to see people in bad situations.

"If I can do what I can to help them, I will," Mr Bell said.

Walk for Don at Human Mechanics, Epsom, March 8, from 10am.
