Running 2 days in a row?

Hi. So I’m training for my first half marathon. My plan includes 3 runs/week: Monday shorter run, Friday long run & Sunday intervals/tempo training. Anyways, I’m recovering from mild shin splints, and I’m worried about getting back… Any thoughts about running 2 days in a row, especially if the second run is harder effort? This has probably been asked million times before but idc if anyone has experience or advice I’d be very grateful. Thanks.
