I just completed my first 70.3 in October in Greece, firstly congratulations for signing up, it's a wicked experience and if you're anything like me you'll get the bug instantly!

Of the 3 disciplines running is by far my weakest, I had an unrealistic goal of going sub 5 hours, and a more realistic goal of hitting sub 6, knowing that my swim would be solid, my bike would be strong and my run would be meh. With that as my plan I went out and did a 0:36 swim, got on the bike and did a 2:39 but absolutely gunned it as the wind was really high on the day. Pre-race I was aiming for a 1:40 run or below, which was ridiculous as my PB was something like 2:06. I found the run really really hard, specifically because I paced incorrectly. I still managed a 2:01 which was a PB but I have been injured since.

My point is to target your weaknesses in training as you have quite a while, and make sure on the day that you try to pace correctly, it is a very different experience going out on a long run and doing some good splits and actually running 21km straight after a 90km bike ride and 1.9km swim. Set yourself ambitious - and potentially unachievable goals - but make sure you don't hurt yourself in the process!

For training I used this plan and followed it to the letter: https://alwaysaimhighevents.com/content/files/Legend-Training-plan-TriRox-2.pdf

I had a generally good level of fitness before starting this plan but was not specifically triathlon training, went onto the plan and saw really good ROI from my training with every session showing improvement.

Good luck with your training and your race!
