Just finished first Sprint Tri, what next?

Hi everyone,
Thanks so much for all your helpful advice to get me through my very first Sprint Tri! I had so much fun and can't wait to sign up for the next one in early November this year!

But first, where I am now: I had written a few developments that happen a week before race, I developed some lung congestion and shortness of breath and was struggling from uphill biking and running due to this, during the week and on race day. Chest xray and bloods all came back normal, possible asthma symptoms from training outdoors says Doc.

Also, I totally screwed up my swim distance (pool swim), 18 laps of 50m not 25m! So I showed up on race day having to swim twice the distance (crawl/freestyle) from what I trained for,( 900m instead of 450m) lol. Fortunately I managed to do this and nonstop, woohoo! Highly advise studying race distances carefully beforehand. :P

Bike went better than I expected, I didn't struggle as much uphill with my current shortness of breathness and I beat my anticipated times. I was mindful of saving my legs for the run too.

The Run WALLOPED me. Firstly, it was about 15 degrees hotter than I've ever trained for and 1/3 of it uphill and I was struggling with breathing. I didn't manage to run as well as I did during training at all and spent a lot of time walking.

So knowing where I am, I would like to tweak my training plan to prepare for my next Tri in November. It will be an Open Water Swim, my first! I think my training will need to be a bit more swim and run focused. Definitely the latter since it was my weakest leg and it really dragged down my times.

I tried creating a training plan from the custom one here on the site but it was showing workout distances instead of times to train in. I'm used to Joe Friel's beginner plan which was all in workout times. I've checked out the 13 week sprint plan too but it doesn't have a ton of detail compared to Friel's plan that I was using. Should I just modify and merge the two? What are some other options I should explore? I have almost exactly 3 months till my next Tri Nov 3rd.

Thanks in advance!
Amy
