Running a marathon improves the health of a runner's arteries
Researchers tested 138 novice runners attempting the London Marathon.
Over six months of training, runners arteries regained some youthful elasticity.
People who were the least fit beforehand appeared to benefit the most.
It took runners between 4.5-5.5 hours, on average, to run the 26.2 miles.
