Tri ing to shift that last bit of spare tyre

Hello,

I have been training for about four years, and have come down from about 250lb / 115kg to 196lb / 90 kg. I am 6'6". I took part in two Super Sprint Tris in May this year, (amazing fun) and have the next one scheduled for Sept. I train about 3 - 4 times a week, very intense cardio, (about 45 min - 1 hour) and have three small children so spend my weekends running around after them (so not much time for working out etc). And I intend to step up to Olympic Distance next year.

I have never been / probably never will be "ripped", but would like to know if there is any way that I might shift that last bit of fat from round my middle. Or should I just suppress my vanity (which I did not suffer from when I was 250lb)? And focus on Tri event performance? Or do I need to train more and for longer?

I have always been a bit of a glutton, and I 'manage' this perpetual hunger with oats for breakfast, protein shake mid morning, usually spag bol for lunch, protein shake mid afternoon, and a normal supper (e.g. fish, sweet pots and veg). I drink moderately (usually wine).

Any practical advice gratefully received.

Thanks.
