New...returning triathlete...ish

Hello BT! It's been a while! I've been off from training for about 5 years and I have slowly been working my way back into it this year, starting back in January.
I started running again, and realized quickly that I am very much out of shape (currently 44 y/old).
Started lifting weights regularly to build back my strength, feeling great with that.
Recently started bike riding with our 9 y/old on the gravel trails and rekindled the desire.
Hopped into the pool for some laps yesterday and it's a full blown fever now.

Not sure how soon I'll be ready to race again, but the desire is there. Just need a cheering section as I restart this journey. Baby steps as I build back into form.
