Björkis Spitfire has ran well but never really got upto his full potential, his career so far has been plagued with small injury problems that has stopped him showing his full potential, with his staying power and his trial times of 17.76 over 295m shows he has very fast early pace, he is coming to form exactly at the right time for the International derby and may well pull off a suprise and fingers crossed he will stay injury free this year.
