How can I use the speed work I did for my half marathon to run a new PB for 10km?
During the half marathon preparation you will have developed a good level of strength and endurance – both good characteristics when targeting a 10km. The advantage of half marathon training is that you will not have lost much speed in your preparation and therefore you should be in quite good condition for a 10km.
After the half marathon it will be important to allow adequate recovery (see above) before starting to touch up your speed for the 10km. If you recover quite quickly then it is feasible to compete in a 10km about 4-6 weeks after the half marathon with the aim of running a good time.
You will have the endurance so just continue to touch this up with weekly long runs of moderate duration. Your focus however should be on interval work and more specifically VO2 sessions to start getting you on track to maintaining a consistent speed throughout the 10km.
