Asian and Commonwealth Games steeplechase gold medal-winner Sudha Singh, 31, feels participating in Sunday's Tata Mumbai Marathon just three months before the Commonwealth Games (April 4-15) to be held in Gold Coast, Australia, will help her improve her pace Down Under. "I haven't run a full marathon after 2016. Hence, I took part in the Delhi half marathon last year to boost my confidence. I'm glad I achieved my personal best (1:11:30s) there and came second."
