Vaidya Rattan Dev Jangra (62) of Hisar will be the only person who will run backwards in the half-marathon (21 km) in Delhi on December 15.
Talking to mediapersons here on Sunday, he said that the organisers had decided to provide him four volunteers during the marathon - two would follow him and two would be ahead of him to keep the track clear. "The time limit to complete the marathon is three hours, but I will finish the marathon in less than two hours," Jangra said.
Jangra holds the record of walking backward continuously for 24 hours. He is an Ayurvedic practitioner in Hansi. The organisers have already examined him medically and given him fitness certificate.
Jangra has been allotted running bib number 15301 E, which carries a chip to record the time of running.
"Running backward is more difficult as it burns 20% more calories as compared to running forward," he said.
