Just be a little careful is all I would say. Looking at Nick’s Strava it looked pretty intense. Do the reps you can as you don’t want to undo all the good work you’ve done in terms of recovery. It also depends what is most important to you, running or the gym. If it’s the former then the gym work should just compliment the running and ensure it doesn’t stop you doing it. All that said, well done for getting in the gym.
