The 31-year-old Sandeep, representing Haryana, clocked 3 hours 56 minute and 39.71 seconds to win the 50km race walk event. His timing was around 40 seconds slower than his own national record of 3:56:00 set in the National Championships here last year.
Jitendra Singh Rathore (3:58:55.82) of Services bagged the silver while S Damen Singh, also of Haryana, took the bronze in 4:00:34.48.
A B.A. second year student from Varanasi, Patel has been training at Bhopal SAI Center since 2014.
The earlier national record in this category stood at 49:16.51 which was set in 2004 by Priyanka Goswami of Uttar Pradesh.
The gold in men's U-20 10km event went to Akshdeep Singh of Punjab (43:04.65). Haryana athletes Hardeep and Manjeet won the silver and bronze respectively in 43:36.62 and 43:36.67.
"In international competitions, you have competitors who push you and you also are given a pace setter through a motorcycle. Even if you remove just 1 second every lap you could make a big difference in your final time."
"These qualifying guidelines are not cut in stone. It's preferable if an athlete crosses these guidelines but we will see later whether an athlete has a chance to win a medal or not. We will do it nearer the Asian Games," AFI Secretary C K Valson said.
Sandeep shifted his training base from Bengaluru SAI Center to NIS Patiala recently and he said he did it due to his problems with coach Alexander Artsybashev.
"I qualified for 2017 World Championhsips in London in both 20km and 50km but he (Alexander) cut out my name and put K Ganapathi (20km event) instead. He put Ganapathi in 20km event in Rio also, instead of me. With Alexander, its is like working under pressure," said Sandeep.
"Under Surender sir, I can train with motorcycle in front of me for 30-40 km which actually happens in competitions. If you are following a motorcycle or like that and if you can walk faster for one second in one kilometer that will reduce your time by 50 seconds when you complete the race."
Alexander, on the other hand, said Sandeep lacked work ethic to be able to improve his timing to world standards.
"Whatever he might say I am not into all these selections. That is not my job. He is a top national level athlete and it had gone into his head."
Ganapathi -- Rio Olympian in 20km -- and Gurmeet Singh made their first foray into the 50km event but they were disqualified during the race by the judges.
