"We had to stay in the Sheraton next to Heathrow but when we arrived it was about 11 o'clock in the evening and the middle of the winter. It was impossible to train outside.
"I started to think about how I could train and then I noticed that my hotel corridor was very long. I put on my shoes and started to run up and down it, and then some of my friends joined me.
"By that time it was close to midnight and people started to come out of their rooms to look at us. Do you know what happened? They all thought it was an emergency and started following us. One old woman was shouting and running down the corridor in her pyjamas."
The memory brings forth a loud guffaw before Gebrselassie's eyes narrow and he gets to the moral of his story.
"The reason I'm telling you this is that I didn't want to miss a day's training. I always tell young athletes the same thing, 'Wherever you go, whatever you do, what must your top priority be? Running'.
"In my life I do a lot of things but I never forget my training. Athletics is in my blood. The top priority must always be training, training. This is a discipline. You have to do it."
Remember, while you're opening up presents and sipping on eggnog, somebody out there is training. With that thought, Merry Christmas!
