If you’ve managed to keep up with your schedule by now, then congratulations! You should again be looking to increase the intensity of your training. Start to introduce running routes with hills and make sure you add a burst of speed to the hills to further build on your new strength in your legs. Make sure to still begin the week with an easy run, say 5-6 miles. And remember to always incorporate at least one rest day, possibly a Friday so that you are fresh for a longer run on the weekend.
By week 7-8, you should be incorporating a couple of runs each week to be running at threshold pace for 4-6 miles, in between a mile warm up and warm down. For some of your runs, include very short bursts of just 30 seconds that will increase your comfort of running at a quicker pace during your half marathon. Running a longer run on the weekend, say 10-12 miles, should also be common place by now. But in the final week before the race, do not be tempted to cram in that extra bit of training. You will not be able to improve much by now and you will only fatigue yourself for race day. In the earlier part of the week, go for an easy run whilst incorporating 1-2 miles at race pace. You may also want to run 3-4 miles in your race day kit, just to make sure everything fits. Other than this, focus on getting enough sleep, eating well and planning your journey to the event. Best of luck on the day and be confident that you’ve done the right training to get you through!
