What a load of utter tosh
Its as serious as you make it FFS.
Guess what – i race olympic distance tri at pro/elite level, i race my mtb at national level pro/elite – it doesnt rob you of skill it just gives you something to do. Structure CAN be part of it but it can be quite fun and satisfying knocking off a race and doing the bits you think you can;t do (like swimming for me which is my weakest discipline by miles. I drink beer, i eat crap food sometimes, i’m about as serious as i like to be and i eat a nutritionally complete diet including gin, beer, spirits, kebabs etc Don;t listen to the knobs – get yourself into it. You’ll find earnest, serisou types in all the clubs 🙂
