Training wise I would do some of the recovery runs as bike rides. My own focus was on getting my running base speed up, the endurance was no problem (except the first one not enough run km during winter...).

One problem is that the bike specific muscles slow down the run, so don't bike too much (advice from my coach, simplified). Don't do hard intervals on the bike now!

Thanks for the tips, appreciated. Bike rides as recovery runs is a good method.
I'm very curious about "bike specific muscles slow down the run". Could you please expand on it a little bit more?
