One night, we got to Kissena but the track was too wet to race on and the officials went to get pizza. Well, the track dried off 45 minutes later and we did some drills. One buddy of mine suggested we do the following format of sprint intervals. Two riders, one sprinting for one lap, leading out the other who would sprint on the second lap. One lap cool down to reconnect, then switch roles. A handful of these made me want to vomit.
You could do one lap on, one lap off intervals alone by yourself.
You can work on Flying 200s, kilos (and your standing start), alone.
Head out on the weekends and hang out and talk to the guys who are there all weekend long. Doubtless they'll have some good input for you.
