Two dozen lucky rabbits feet doing cheap to all you paranoid runners out there.
Hi Max, welcome to the sub 4s, achieving your goal will be down to you & the training you can do, looking at what you have said you will need to increase your long runs over the next few weeks. Are you doing any other training like speed & hill work?
Remember that you should look to enjoy the day first and foremost so make sure you do not set to high a target which will not allow you to do this.
Benicetome, I think I may take you idea regarding training tips a stage further and just ignore the training.
Happy running
CA
