Action continues on Wednesday (28th) at the Lima 24 World Athletics U20 Championships, which sees 1,700 athletes from more than 130 teams taking part.
Here are three things to note about Estadio Atlético de la Videna.
100m spotlight
Five finals will be held on the second day of competition in Lima, with the evening session culminating with back-to-back finals in the women's and men's 100 metres.
On the women's side, it will be a close race between Adaeja Hodge of the British Virgin Islands and Alana Reid of Jamaica. Both swimmers looked calm and confident in the heats, with Hodge leading all qualifiers (11.45) followed by Reid (11.46).
Hodge and Reid bring world experience that could bolster their hopes of winning, while Great Britain's Nia Wedderburn-Goodison was the only swimmer to break 11.50 seconds in the heats, clocking 11.47, and will be fighting for a place on the podium.
In the men's race, South Africa's Bradley Nkoana will be looking to improve on the record. With a personal best of 10.03 seconds and a silver medal in the 4x100m at the Paris Olympics, Nkoana is the obvious favourite to win. He topped the heats in a time of 10.27 seconds.
Japan's Nishioka Naoki, who also clocked 10.27 seconds, looked strong and composed in the first round. Nkoana's compatriot Bayanda Walaza, who clocked 10.28 seconds in the heats, is in line to join Nkoana on the podium. Pre-race standouts He Jinxian of China, Gary Card of Jamaica and Pripol Boonsong of Thailand could also be considered favourites to win.

Heptathlon Heroes
Keep an eye on our incredible women's heptathletes as they complete seven events over two days of competition.
Drama unfolded from the beginning, with podium favorite Sarolta Christi of Hungary falling and being disqualified in the first event, the 100m hurdles.
Jana Koščak of Croatia remains the favourite to win the overall title and if he continues his good form in the remaining events he could be in for some impressive points.
Behind Kosciak's sheer strength, Adela Tkacova of the Czech Republic, Lucia Acklin of Switzerland and Alina Chistyakova of Kazakhstan will all be aiming for medals.

Long Jump Redemption
The women's long jump had an unusual qualifying round, which could lead to an interesting and potentially unexpected final. Surprisingly, given the competitors' personal bests, no athlete achieved the automatic qualifying mark of 6.40m. The final was decided in descending order of first round results.
Spain's Laura Martinez led the qualifiers with a season's best of 6.36m (the only season's best of the field) and will be hoping to continue that form in the final. Her personal best was 6.46m in 2023.
Favourites Prestina Oluchi Ochonogor of Nigeria (6.28m) and Sophia Beckmon of the United States (6.16m) also advanced but will be looking to bounce back in the final, as they both come to the event with strong personal bests of 6.79m and 6.86m, both set in 2024.
