I like Daley Thompson because despite being so successful he didn't like all of the events that made up the decathalon.
He has four world records and two Olympic medals. Commendable.
Yes! He was very good at most of the events but not so keen on the long distance running. Fortunately he built up enough points to win regardless of how he did in the distance races. 
He is considered the greatest decathlete.
I didn't know that but it doesn't surprise me. He was certainly excellent and beyond that also very inspirational. He was a pure athlete in the sense of being against drugs etc. One of his competitions required participants to wear a top with a Guinness logo and he refused because he didn't approve of alcohol. I think he might have been penalized. Good for him!!
He joined the British team for the Olympics when he wasn't even 18.
Yes, very successful early on. Some time after leaving professional athletics he was giving the options of working in a couple of outdoor clothing chains and he said he chose to work at Cotswold Outdoor Store because he didn't want to be involved with decathalons now.
He has a mobile game called Decathlon. 
Is that the one for the ZX Spectrum? Did you get my joke about him not wanting to work in Decathalon stores because he had moved on from decathalons?
I guess I missed that one because we don't have those in Texas. The one I'm referring to is for IOS and Android phones.
Sorry, I should have globalized my attempts at humor! I wasn't aware that he had games realized for mobile. I'll go and look for it!
You should. Hope you have a great day and good luck!
