Vámonos Coaching knows how important it is to maintain speed, especially when you're deep into your training plan.
It's easy to start off fast and end with less pep (we've all been there). Here's a workout that'll help you better control the gears.
2 mile warm up
3 x (2mi at 10k pace, 1/2mi at 5k pace) *2mins rest after each set
2 mile cool down
You could adjust the sets as you get more comfortable with this format (e.g. upping the ante to 4-5 miles at slightly easier paces for those going after the marathon).
Happy tearing it up out there!
