Sprinting 101: How to Be Explosive (Sprinting Thread)

I have more basic questions about sprinting. First, what distance/time is considered a true sprint? I’m interested in about 1 minute sprints/efforts. My basic question is…

Should I be in the big or small chain ring for 1:00-1:30 min relatively flat all out efforts?

I realize everyone is probably different in this regard but I really don’t know if there is a best practice on this. Overall, I’m probably a spinner. Historically I might have done better in the small ring but am not sure. Lately, I’ve been doing these in the big ring but find my legs are cooked before the end. Its probably a combination of factors (like going out too hard) but I’m looking for more information.

BTW, great video!
