New research from Australia reveals that running long-distance runs can
slow the ageing process by protecting
telomeres, the part of the body that stops
the genes from fraying. There's still a lot to learn about how telomeres work, and this was a fairly small study, but the early evidence is fascinating. You can read
the full story at the Herald Sun News.

Professor Fadi Charchar and PhD student Joshua Denham analyzed the DNA
of 67 ultra marathon runners to see what the impact of running long
distances had on the length of their telomeres. Runners in the study had an average age of 43, but their biological age was just 27. They are now also looking to see if similar results can be achieved with high-intensity interval training.
Telomeres are structures are made up of DNA and protein and act as protective caps on the ends of chromosomes, and influence how quickly cells age. The shorter the telomeres become over time; the faster the cells deteriorate. The
findings, to be presented at the Australian Society for Medical
Research National Conference, found ultra-marathon runners clocking up
40-100 km a week had 11 per cent longer telomeres.
"This 11 per cent difference adds 16 years to your life expectancy," Prof Charchar said.
So not only does it make you feel better, it could be adding years to your life!
