Participants will rotate through jumping and throwing activities, running and wheelchair races, and finish with a fun relay.
Sport Whanganui disability and inclusion lead Sarah Craig said the event was designed to ensure every participant felt welcomed and supported.
“The All-Ability Day is about creating a space where everyone can take part, have fun and try new sports and physical activities in a way that suits their individual needs and preferences,” Craig said.
About 70 young people, with their teachers and support people, participated in the inaugural event, Craig said.
“We are excited to welcome everyone back and hopefully see some new faces ready to give it a go and be active,” she said.
The programme will be split into two sessions with primary school students in the morning, followed by secondary students in the afternoon.
Spectators are invited to watch the action, with the activities starting at 10am.
The Whanganui Secondary School Athletics Championships will showcase track and field athletes as they represent their schools.
About 350 students are expected to take part, including athletes from all Whanganui secondary schools plus Rangitīkei College, Ruapehu College and Taihape Area School.
Event winners will qualify for the North Island Secondary Schools Championships in Papakura on March 28-29.
Sport Whanganui, Athletics Wanganui and community volunteers are supporting the event.
Students who want to take part in the All-Ability Day can register through their school.
