A daily 5k run and squash twice a week?

You're even worse than delusional. Get ready to say goodbye to your Achilles tendon.

Indeed; build in at least one rest day, and replace one of the runs with a swim or a bike ride. Once you get tendinitis, it hurts, it slows you down, it can (indirectly) cause muscle atrophy on the affected limb and it doesn't go away easily, as my right knee demonstrates.
