i have to wear my glasses also. wrap them up in something to keep them dry while you are swimming. Does your helmet have a visor on it. If so that will help. Have you every rode with a baseball cap under your helmet that can help keep some of the rain off your glasses. If you need to stop and wipe them off just be real careful and make sure you pull right over to do it. Remember everyone will be racing in the same conditions so it will not feel so bad when you are out there training in crappy weather. Let this be your learning experience. The most important to make sure you have warm stuff to put on for the bike ride. It could be cold. My tri suit does not have pockets either but i use a belt that i can put stuff in and clip it on for the bike ride take it off for the run. Have fun. You got this and remember it is a learning experience

The water temp should be fine. Good call on the 2 pairs of socks. I really worried about my glasses. I cant ride without them, and I dont have little windshield wipers for them..lol..plus my tri suit doesnt have pockets like my cycling shirts do..now its up to 90% chance of Thunderstorms..yep..my luck..

sorry to hear about the rain. bring a bag in case the ground is wet. some people cover the bike seat up but you are wet from the swim so it does not matter. you might want to bring long sleeve to throw on for the bike. i know when i did mine in the rain my hands were so cold. be careful riding. don't worry about time just do it. if you like to run with socks than make sure you have a spar so you can put on after the bike ride. do you know what the water temp. is. there is cut off for safety on what they will allow a swim to go. hope you get the swim in but be ready to run ride run. like i said done a few like that. you are all set to swim and bang they cancel it. good luck

Thank you for your input!

I tend to get a better workout on the treadmill, probably because I like a treadmill more. I vary my speed and incline throughout for more of a "HIIT" kind of workout.
