Tri newbie mama of 3 here

Hi everyone! Im so excites to find this site and learn from all of you who have already done triathlons or who have been training for a while.
I am 37, have 3 kids, 7, 5, and 7 months who are joining me on this fitness ride. My oldest is doing his first kids tri next weekend and we are all excited.
My first sprint tri is September 1st. Ive been running again for a few weeks, but my only previous fitness experience was about 8 or 9 5k's a few years ago before foot problems took over.
My running game is slow, my biking training is pulling a kids trailer and swimming hasnt even started yet! Its okay though. Ill just keep chipping away at it!
