RB34 suggested a pretty decent set-up you could try.
I wouldn’t do sled drags or anything like that. That is going to be a waste of time for running. The work you have on the bike sounds like a good start, but you could also do various sorts of medicine ball circuits (throws and other lower intensity exercises for high reps), general strength circuits (various bodyweight based exercises, circuit style, with short rest), and even running in place. Pool work would also be good. I would even go as far as to say doing treadmill walks (~30 minutes on a moderate inclide @ 4.5 speed) could help with recovery. Another option besides doing tempo is just doing a long warm-up, which will let you get some more running and movement type stuff in there without the same stresses as running.
