RKC's 2023 50k Suburi Winter Challenge

2023 RKC 50k Suburi Winter Challenge

The RKC's 2023 50k Suburi Winter Challenge will take place from 1 JUNE - 31 AUGUST 2023 (92 days), the "winter months" for those in the southern hemisphere of the world such as us here in South Africa!

This year's challenge has a slight twist, which consists of incrimenting the number of suburi by 10 every day until the end of the challenge!

"Suburi", or "practise swings", can be done with a shinai, bokken, iaido or jo. For those tough days, even an air-sword or a rolled up sheet of paper will suffice! Provided it is done CORRECTLY, then it will be accepted as part fo the challenge.

On DAY 1 (1 June) the challange will start with 90x suburi. Then, as each day progresses, 10 more suburi will be added to the previous day's target (i.e. Day 2 = 100x suburi; Day 3 = 110x suburi; Day 4 = 120x suburi; etc). By the end of the challenge on Day 92 (31 August), the final suburi to be done on that day is 1,000x suburi! In total, if one did every day consistantly, the total suburi done will have been 50,140!

Consistency, planning and accountability is KEY!

DM if you're up for the challenge, and you will be added to a WHATSAPP accoutability group!
