The former world solo 24-hour champion and Editor of Enduro Magazine was unable to be revived after team mate Shaun Lewis could not wake him last Wednesday morning.
He and Lewis were competing in the gruelling 8 stage 722km Absa Cape Epic in South Africa, the largest full service mountain bike stage race in the world.
On Monday it was released that Williamson had an undiagnosed heart condition that had caused his ventricle to grow larger.
Williamson's participation in the event was not considered a factor in his heart failure Williamson's partner Niki Fisher told www.cyclingnews.com
"It could have happened to him as he was sitting at the computer, or just lying in bed"
Williamson had blogged regularly before his death, describing the first 117km of the race as the most challenging physically and mentally.
"This was the hardest point of the race for me and I was beginning to wonder what I was getting myself into," he posted.
The Christian race is just as hard and as long.
It is easy to be swept up in the chaos of worldly pressures, wants and desires and forget who we are meant to be living each day for.
A great quote circling around at the moment states that "The greatest freedom you can experience is to finally realise that your life is not and has never, ever been about you."
Paul in Philippians reminds us make our goal the heavenly prize that God has called
us to through Christ Jesus.
It is a goal that we must not take our eyes off for a second, our time here on earth is
short and we do not know the hour in which our Lord will call us home to be with
him.
When our time comes let us be able to say "I have fought the good fight, I have
finished the race, I have kept the faith" (2 Timothy 4:7) even if those who remain feel
that our time on this earth has been cut short.
