That’s exactly what we do on a Sunday, followed by general work.
Regarding the split runs, I reckon one session will be enough.
Do keep your sprint volumes down, I made the mistake of keeping the volume on the sprinting pretty high, thinking my athletes could handle 4 sets of 60’s. And they could, they completed the sessions and were going fine, or so I thought. Even when I reduced the volume and increased the recoveries they just could not get any faster and it took a long time to get it back. I know other users of this site who have had the same problem. I now keep it at 2 sets of 4, even 3 sets left some of them flat.
