Upon arrival, you learn that she is going to do "a few laps." Fortunately, your light kit included the Canon RF 70-200mm F2.8 L IS USM Lens, an impressive lens that is sports-capable, and you were able to capture some nice pics of your daughter on the track. Since you were actively photographing, you also captured some nice pics to share with her teammates.
The 20-fps drive mode meant that the perfect body position could be captured in every pass, despite the relatively short optimal framing window the 70-200mm focal length range offers. Perfect body position except that you were positioned near the starting line where your daughter glanced at her watch as each lap was completed. Eye detection AF meant the framing was the photographer's primary remaining job to be concentrated on during the race. Well, their primary job until having to process the over 1,000 in-focus images delivered by the Canon EOS R5's 20 fps drive mode in a short time.
The image quality at 20 fps was superb until the sun began to set. Then the flickering stadium lighting began to show some mild banding in your full electronic shutter images. Fortunately, only the last lap was affected by this condition (which could have been avoiding by using the still-fast mechanical first curtain shutter).
After the time trial ended, cool-down runs were over, and the team meeting was finished, your daughter says, "Hey Dad, can you take a team photo?" Your only valid response to this question is "Sure!" As you care about your images, you are not willing to make this a simple snapshot. That these kids have worked hard for years to make this team makes a good team photo especially important.
Your first assessment is the available lighting. This one is easy. The sun set a long time ago, and the only lights available (you did not bring strobes) are the four large stadium lights, two evenly located on each side of the field.
You know that the image background is very important and decide that the home stadium seating provides a clean, non-distracting background, along with giving the image a relevant location.
To get balanced lighting and a symmetrical background, you move the 19-member team down to the centerline of the soccer field inside the track. As mentioned already, and as is frequently the case, the stadium lighting was the flickering type. The Canon EOS R5 and R6 can avoid that issue for you, but a 1/100 second shutter speed is slow enough for the flicker to not cause a problem without using the flicker avoidance feature.
The team was very cooperative with great attitudes. Upon seeing how the double-cross lighting with the stadium background looked in the image review, the excitement increased, and additional photo requests begin flowing in: individuals, with friends, with boyfriends, with roommates, silly photos, tough and serious poses, etc.
The RF 70-200 was again the perfect lens option. The widest focal length is long enough to force adequate subject distance to eliminate group photo perspective issues, including the people in the front row appearing much larger than those in the back row (keeping the rows close to each other also helps in this regard). The individual and small group images were also easily captured by this focal length range.
Your dinner was late this evening.
After spending many hours processing and uploading the images to a private SmugMug gallery for the teammates to access, you wonder if it was such a good idea to take the camera in the first place.
Of course, it was.
OK, maybe I am not hypothetically speaking in this case. However, this scenario is a quite common one — be ready for it. Consider using the same lens and easy subject-on-night-sports-field strategy for your athlete subjects.
