Event Detail
Lake Saroma's November 1-Month Online Challenge is a separate 100 km virtual category from the two-month Stage 2 challenge already listed in ARC. Participants accumulate distance on their own routes using TATTA.
Accumulate 100 km in November
Complete at least 100 km between 1 and 30 November 2026. Multiple runs may be combined. Only TATTA activities recorded as Running or Trail Run qualify. Walking, Hiking and Cycling do not count, and manual distance entry is generally not accepted.
The same RUNNET ID must be used for registration and TATTA. GPS-watch users need to synchronise eligible activity into TATTA before the event closes. Activities crossing into or out of the event date window are excluded.
Eligibility and registration
Participants must reside in Japan and have a compatible smartphone. No age restriction is published. Registration closes on 27 October at 23:59 Japan time or earlier if capacity is reached.
Four package prices are offered for the same 100 km target: JPY4,990, JPY6,990, JPY8,990 and JPY12,990. RUNNET adds a 6% handling fee because all package prices exceed JPY4,000.
Package and delivery notes
The package selected determines the participation reward. The official page specifically notes that the JPY8,990 course includes shell-on oysters from Yubetsu, with delivery around the end of the event period. Other package contents should be confirmed on the official Saroma online page before payment.
Credibility
This challenge is organised by the R-bies Sports Foundation and registered directly through RUNNET. It is a distinct one-month category, not a duplicate of ARC's November-December Stage 2 listing.
Race Pack Information
No common collection venue. Package items are delivered domestically according to the selected course. RUNNET specifically notes the JPY8,990 oyster package is expected around the event's final day; confirm other dispatch timing before entry.
