Tip 2/50. **X Warm up properly on the day as if you pull something you won’t get a PB. Get a few race pace strides in that warm up. Personally, I don’t jog a mile to get there…I cycle or drive. The consensus view these days that any stretching you do before a race should be ‘dynamic’. Look at track cyclist between races. They stay ‘warm’ by using stationary trainers for a reason – simplistically the muscles are pumped full of blood right from the start and are ‘ready to go’. Jogging to the start might actually be a good idea.
