Hi Hero,
Your simplest approach in this situation is to reapply your plan with the new race day applied and follow the last 8 weeks of the training.
Keep your eye out in 2023 as we will be releasing bridge plans for situations like this but they are only up to 6 weeks. So in this situation my recommendation stands. Remember, you will have already built a good amount of fitness, so you don’t need to overdo things in that 8 week to have a good results at the second race. Those 2 weeks of rest will also be important to a good second build up.
