Half marathon route review :- I think the course is the most challenging half marathon road race (actually, it was under-distance. GPS watch showed 20.18m ). To describe it as a hilly course would be an understatement. The elevation gain in Strava shows 1000m while in Garmin shows 841m. There were many types of hills; short+steep and long+steep. The event was well-managed. There were adequate water stations and portable toilets on the course.
