Christopher had dreamt of competing in triathlon for years but her health conditions had seen her doubt her ability to participate.

But this time around, despite suffering fibromyalgia, neuropathy, and a form of bone marrow cancer, all of which saw her undergo multiple operations leading to constant pain and fatigue, Christopher was determined to compete.

She was even told by doctors that she would be wheelchair-bound.

These conditions and disabilities cause Christopher's muscles to spasm, or as she calls it "do a little twerk every now and then".

Yet she has a remarkable zest for life, and determination to 'do whatever she can.'

So much so that with the help of Elite Energy and Jervis Bay Triathlon Club's Pat McGill, Christopher got to the start line on Sunday for her very first ' Try A Tri' event.

After overcoming her anxiety, she quickly got in the water and completed the swim leg and headed up the stairs, following a little 'beach twerk'.

She then rode her trike on the cycle leg, before starting her run which she walked with an aid, so they could 'hold her drink bottle'.

Her race was completed by striding up the red carpet, where her joy and excitement were overwhelming.

"I could not believe what I had just achieved," she said.

Following the race, Christopher thanked the Jervis Bay Triathlon Club for its ongoing support.
