Double runs are a great way to increase run volume while lowering the chance of injury compared to if a similar run volume was completed in one session.
The key point in this approach is that it allows for a recovery and refueling period between runs.
I often use such a strategy as a great midway point when athletes are looking to step up the distance of their long run. This could equally be because they are new to running or maybe they are looking to tackle a longer distance race. The approach is equally valid for every runner regardless of ability as volume is relative to the individual.
A double run could be completed on the weekend or mid week.
Why not wake up early to see the sunrise and enjoy a morning run before work. Start the day feeling vibrant! After work slide another cheeky run in, suddenly you have quite a solid day of training. Nice work!
