Marathons – not what they used to be

Sir, – According to Ultan Ó Broin, “pretty much everybody finishes a marathon these days” (April 11th). I agree.

Marathons? Since the age of about 10, I’ve started them many times and have never had any difficulty in completing them. I’ve also known for certain that I’d finish each one and have always felt great afterwards. And that was both before and after they were renamed Snickers in 1990. – Yours, etc,
