Had a letter from Welsh Traithlon, events that they sanction in 2011 will have a minimum day licence cost of £8.,( was £2 this year) Its up to race organisers how much they actually charge, so for a lot of races its likely to be a tenner. Its meant as a push to get more people to join British (& Welsh ) Triathlon.
There is some exemption for 'novice' events, but I dont know what classifies a race as 'novice'.
I believe that for English Triathlon sanctioned events its only going to be £3.
Just something to have in mind when you are planning next years races. For the race I organise (Blaenafon) it will mean almost a 20% hike in entrance fees for non BTA members, how this will effect entries I dont know. For some really cheap races it means that the cost will almost double for non BTA racers. A local aquathlon series I race in might now become £18 per race!
