Hi from Central Queensland, Australia!

Hi everyone, I am 34 year old mother of two young boys. I started training for my first sprint triathlon about 6 weeks ago; it will be held at the end of January. I am reasonably fit; I can complete the required distances and some but am not sure how I will go when I have to put it altogether! I just bought a second hand road bike which I am keen to get out on. I train a lot indoors on my treadmill and stationary bike due to the heat, it's 40c Celsius most days lately, and also because I train at night when my boys go to bed and I (obviously) can't just leave them and go out to train! Looking forward to hearing from other newbies ??
