Hi Sophie,
I hope your having a good day! I wouldn't worry to much about the triathlon people, I'm sure they will contact you soon. Sometimes those people can take a long time to respond. Hang in there. And on the breakfast, Everyone deserves to eat a nice breakfast, that's what our bodies need to fuel up for the days workout. And it seems like your doing really good in getting to the gym and working out. Hang in there and keep it up!! Have a good rest of the weekend.
Kim
