Participants can dress as their favourite pop star or their musical icon and run 5l, 10k or 21k.
People decide to start running for a number of reasons - health, enjoyment or because they have signed up for an event.
Hannah Seltzer will be pounding the pavement as part of Brighton Run2Music, which takes place on May 11 on Maderia Drive.
She said: “I am definitely not a runner.
“I’ve always hated running as I find it quite boring, but I felt like this was the year to do a challenge and Brighton Run2Music was the first choice due to it making running fun.
“Running / hobbling 10k will be a huge challenge for me but no matter what, I’ll be forcing myself to complete it.”
The Brighton resident has worked for charity Rockinghorse Children’s Charity for four years as its challenge event fundraising manager and will be raising money for this case.
“I wanted to run for Rockinghorse because they support Chalkhill Child and Adolescent Mental Health Unit, the only in-patient mental health service for young people in Sussex,” she said.
“This project is extremely close to my heart and I feel lucky to be able to fundraise for such an amazing place.
“I would never wish a mental health illness on anyone but least of all children and teenagers. The patients at Chalkhill are incredible and inspire me every single day. They deserve absolutely everything to help make their recovery the best it can be.”
Rockinghorse is a Brighton-based charity that has been supporting children for more than 50 years.
It was set up in 1967 by Dr Trevor Mann, who recognised there was a real need for additional resources to improve healthcare services for sick children and babies.
It is the official fundraising arm of the Royal Alexandra Children’s Hospital (the Alex).
It also supports the Trevor Mann Baby Unit (TMBU) based at the Royal Sussex County Hospital in Brighton and its sister site, the Special Care Baby Unit (SCBU) at the Princess Royal Hospital in Haywards Heath.
Brighton Run2Music is a colourful and entertaining running event which encourages people to all ages to run together while listening to live DJs and music on big speakers along the course.
Runners and spectators will be entertained by a DJ, dancers, gymnasts and musicians and there will be prizes for the best fancy dress.
Hannah said: “Brighton Run2Music is the perfect event for a beginner, like me.
“It takes place in a great location and has all of the elements of a fun run whilst still being a challenge, so I knew it would be the perfect challenge for me to take part in.
“That particular weekend is also The Great Escape Festival in Brighton so the city will be buzzing with an amazing atmosphere so I’m sure there will be a lot of support on the route.”
The run’s charity partners include Rockinghorse Children’s Charity, Marletts hospice and Rhythmix.
The event is organised by the team behind Brighton & Hove Triathlon.
Hannah said: “I’m very excited for it to be over.
“All jokes aside, I am extremely excited, it will be an amazing day and I can’t wait to soak up all the atmosphere and complete the challenge whilst raising money for an amazing cause.”
