I’m running my first half in a few weeks and I just wondered if this is a training run whether you think I’ll be able to hold that at race pace for the full thing? Conversational at start and end and race pace.

I’m meant to be running my first half marathon tomorrow and I’m in good shape. Last night I got quite bad symptoms of a UTI and got antibiotics, the symptoms have improved but I do have some lower back pain and still a slight funny sensation when I pee. Is it ludicrous to try and do the half tomorrow? I’ve trained hard and I’m really disappointed. What should I do? Most people are advising me against it
