When you pin on your number and line up to race, do you expect to win? Do you put in more hours training per week than you do at your job? If you answered yes to either of these questions, you are not a Pack Filler.
If you find yourself 44 minutes into a frozen, mud bog hellscape of a cyclocross race with the leader about to lap you, but instead of sitting up and ending early you bury yourself to get across the line just so you can suffer for one more lap, you are a Pack Filler.
If you could podium every race as a Cat 3 but choose to push yourself as a Cat 1, even if it means they are finishing up awards and tearing down the course tape before you finish the race, you are a Pack Filler.
Never First. Never Worst.™ That’s a Pack Filler.
