I’ve been running 5k 3x a week. But tonight I really struggled and my legs really ache. I’ve done my usual yoga stretching and did a 5 min walk warm up. Does anyone know why this might be?

Pre run stretching should be dynamic, as linked to in the guide to the plan but static stretching immediately after every run, nhs.uk/live-well/exercise/h... while muscles are still warm and supple, pulls out contractions, avoiding carrying tensions into the next run and also improves recovery by improving blood flow, as recommended in the guide to the plan.
Many people do not hold their stretches for long enough or put enough effort in. Hold post run stretches for 30 seconds and make sure the pull is strong enough to be on the verge of discomfort.
