Edinburgh's historic Grassmarket is to be transformed into an uphill race track for one night.
BMX bikers, mountain bikers, road racers and fixed-gear cyclists will compete in a 170-metre sprint across the Grassmarket's cobbled streets and up the challenging incline of Victoria Street.
Hundreds of cyclists will compete in Scotland's first Red Bull Hill Chasers challenge on March 30.
Red Bull Hill Chasers is the UK's only multi-discipline uphill cycling race, and has been previously held in Bristol and Malaysia.
Around 500 bike enthusiasts will get a chance to race against their heroes, including world-renowned riders Michal Prokop and Jack Pullar, and attempt to prove the supremacy of their own biking discipline.
Racers will take part in an individual, timed hill sprint and the fastest 30 riders from qualifiers will be selected for the main event where they will go up against 10 elite cyclists.
Prokop, three times World Champion four-cross cyclist, said: "I'm really looking forward to visiting Edinburgh for the first time for this year's Red Bull Hill Chasers. The race atmosphere is going to be amazing."
Neil Cousins of Charge Bikes, which will be supplying custom-made bicycles to the winners, said: "It is always a highlight to see everyday riders coming to an event like Red Bull Hill Chasers and racing the pros, sometimes beating them too. The racing is definitely going to be fast and furious."
Edinburgh Council's festival and events champion Steve Cardownie said: "Red Bull Hill Chasers is the ultimate 'battle of the bikes' and a great opportunity for cycling enthusiasts to not only test their skills, but to race against top bike athletes from across the UK.
"We're delighted to welcome the event to Scotland for the very first time. There's a huge cycling community here and I can think of no better backdrop for this exhilarating challenge than Edinburgh's dramatic Old Town."
