I'm riding gear cycle with descending path, it's trible area so I've only this option. Also I'm not coming in top 5 weekly so I'm not sharing a report for reward but I'm sharing strava report only for passion. Also it's possible 13 Km in 13 minute because in our area people complete 5 km race in 25 min. So it's not hard to complete 13 km in 13 min.

Thanks sir for your valuable input in my post and productive comment.
