Thousands of athletes of all ages will converge on University City for the 124th Penn Relays this weekend, including a number of Olympians. Superstars like Justin Gatlin grace the Relays practically every year, but there are some high schoolers and collegiate athletes that will also draw eyes this weekend.

There's no shortage of big events to catch over the three days of Penn Relays this weekend, but with so much action going on, it can be a bit overwhelming to decide which ones are must-see. With that in mind, here are five events that you certainly won't want to miss.

Natalie Stefan joined Penn women’s lacrosse as a midfielder, but she will leave the program as a defender. After suffering multiple ACL injuries over the course of her college career, the senior has moved to a new role on the team, and she’s thriving.

The No. 10 Quakers (11-2, 5-0 Ivy), the only undefeated team in the league, can clinch at least a share of their third straight conference title with a win, while the No. 18 Tigers (8-5, 4-1) can create a three-way tie atop the Ancient Eight standings by pulling off the upset.

It’s tough to have a shot at victory and come up just short.

On Sunday, Penn softball completed its three-game weekend series against Cornell. The Quakers won two games in a Saturday doubleheader before suffering an 8-4 loss on Sunday.

In the final meet before the 124th annual Penn Relays next weekend, the Red and Blue looked more than prepared as they tallied a total of five top-ten records in program history.

Belodeau had already comfortably broken the school’s single-season freshman points record entering the weekend, but even in such a historic year, this might have been her top performance yet.

The movement, sponsored by the Penn Women in Computer Science student organization, aims to “putting a face to these statistics."

Led by five different players each securing at least five points, the Red and Blue held on in a 24-13 victory, maintaining heir undefeated record in the Ivy League and setting the school record for goals in a conference game in the process.

Philadelphia is becoming a national athletic powerhouse, and Penn's tennis program is part of the reason why.

With the Penn women ranked No. 1 in the USTFCCCA Mid-Atlantic Region and the men up at No. 4, it’s no secret that this entire season has been historic for the Red and Blue. But ahead of this weekend’s meet, here are a few specific athletes and teams to watch out for.

After Penn softball's seventh-inning rally came up short in a 10-6 loss, the team has to regroup quickly for the games that really count.

The cox is, quite simply, the coach of the boat. Sitting typically in the stern (or the back) of the boat, the coxswain’s job is to steer the boat.

While the Ivy League might be known for its prowess in academics, there’s another set of ranking lists that are a familiar home to the members of the Ancient Eight: the national men’s heavyweight, men’s lightweight, and women’s rowing rankings. 

In the case of rowing, the early bird catches the brutal, strenuous daily workouts.

The majority of competitions for Penn men and women’s rowing are relatively nearby and don’t require too much travel, but for a few exciting trips each year, the teams get to leave the Northeast and compete far from home.
