Completed my first triathlon today (JerseyMan). It was similar - but not exactly - Olympic distance. Write up below if anyone interested. As always, feedback welcome!
Lead up:
I packed what I needed for the race and had everything necessary. That was great. Had what I believe to be appropriate nerves going into the race. Definitely felt nervous but not overly scared or what have you.
Pre race
Got a good spot and set up was relatively easy. I did a walk from the water to the bike to make sure I know where it is. All was going well until I discovered that my timing chip was broken which created a bit of a mad scramble to get a new one, get into my wet suit, and get out there for the swim. 2 casualties: 1) forgot the pre swim gel I intended to take and 2) didn’t get to do a swim warmup. That said, wet suit went on easy and magic 5 goggles worked a treat.
Swim:
Definitely got flustered and overwhelmed at the swim start. A few factors: 1) we had to swim through seaweed which was weird 2) had a small fright looking down into water and realizing can’t see anything 3) cold water. Windup was I took a very indirect line to the first buoy (well past it). BUT, then I got the swing of things, calmed down, and the swim honestly was pleasurable. The wet suit is magic. I was totally in control. Got ran into and ran into some people but overall good amount of room in the water but nothing crazy. Biggest issue: I suck at sighting. Will send a copy of my watch map which shows I’m zig zagging a fair bit. Ended up swimming an extra 150 yards because of it. All in all, very successful for first open water swim. Was not a catastrophe. Stood calm. Made the swim. Learned some lessons. Have some confidence moving forward to continue building swim. Honestly, swimming with wet suit feels like cheating - feels like all of the pool technique doesn’t matter and actually I’m streamlined anyway. Which is not to say I’m not hungry to build technique - just that it’s a proper advantage.
T1
Got the suit off my top half super easy. My feet are little baby feet and don’t love running on rocks / chip seal to transition. Found bike easily. Struggled getting my legs out of wet suit and got dizzy. Had to sit down and collect myself. Eventually got wet suit off and got ready. Overall, 4:50 is ~2 mins slower than it needs to be for this race but not a terrible T1. I do think I may get dizzy in future as I sometimes get light headed standing up and I can imagine that happens when you go from horizontal to vertical. Welcome tips for getting legs out easily. Anything to lean on? Not going socks in cycling shoes seemed like a good decision - got my stuff and left
Bike
Multiple storylines here. Coming out of water I was passing everyone. I was only passed by 2 people (maybe 3). Definitely took ground on people whenever road tilted uphill and lost on people in TT bikes elsewhere. Would say the field was 70% on TT bikes. Forgot to start the bike computer for like 9 miles (doh) but eventually started it. Power was really strong. On Lachie’s advice, I road to a NP of 240 (~80%) and honestly felt in control entire time. Definitely not easy but also not crazy. I think 230 or so is a fair target on 70.3. Tri suit felt great and no saddle issues (which is amazing given how thin the chamois was). Eager to put this into BBS and see what CdA it calculates. This course was very rolling 2300 ft on 32 miles) and very few drags where you could just get aero and put down watts. (Will add screen shot of elevation). Overall speed was 18.8 which I was disappointed by but that’s why I need to put into BBS to see what I should be going for in terms of speed on a less rolling course. Fuel was okay - but maybe slightly not enough. Took 2 500ml bottles with 30g of carbs (60 total) + 1 PF90 gel + 2 clif bloks (-15 carbs). So for ~2 hours that = 165. Then finished remaining bloks on run (35g carbs) for 200 total on 3 hrs. Will continue to tinker a bit here - I think this is not far off but still some dialing. I have 2 hrs at 70.3 race pace next Sunday (230W) so might be good to try that then.
T2
Got bike in, racked. Overall time was ~230 but it took me too long to get my tight feetures socks on. Any tips? Had everything organized and got going. Also no speed laces which I’m okay with. Opportunity to get a minute back but also not bad for first.
Run
Lord this was a tough run course! 388 feet on ~6 miles. Always either going up or down, including one very steep dirt road. Started out feeling heavy breathing but tried to ease into the run and follow Lachie’s advice re negative splitting. Finished first loop in 16:24 and started to find a rhythm. Second loop was down in 31:40 or so, meaning the 2nd loop was ~1 min faster. Then burned home. Splits were 745, 729,727, 721,711,709. This was probably a bit harder than I could run for 21k but this was also a very on/off run with either heavy work getting up a hill or trying to float down. Overall pace of 724 off bike = solid
Overall finished in 2:59. 3rd in my AG (though that’s misleading because it’s a small race and I would have been first in 30-34 and off the podium in 40-44 
I have clear areas to improve (swim sighting, T1) and BBS estimates my CdA as 0.37 which is probably the biggest thing that can be changed. But not ready to take on a new bike just yet (need to ensure I am committed to the sport)
Also thank you to @giventotri who inspired me to write this with his reports
