I like this plan. I think 2 x S&C per week is plenty if we use the machines and cover all in one go (core, legs and arms). That’s all Paul does and he’s transformed his body over the past 2 years, so that’s all we need to do. I think if you can get a third gym session in, either Monday or Wednesday, might need to be solo, where you do cross trainer that will boost your points and allow you to build your endurance before introducing a 2nd run again.
We keep parkrun in there every week and if you’re doing that with a 10 min WU & CD you will be fit enough to run the 5 Miler too.
Not much else to add really. If this goes well the biggest boost should be to your aerobic fitness and hopefully the continued strength work will allow you to keep running.
