Distances

• 100K
• 100 mile

Qualification standards differ by distance. Entry to the Plain 100 mile requires completion of a TRAIL 100 mile or the Plain 100K; comparable events of similar difficulty and self support will be considered. The Plain 100K has no formal qualification requirement but organizers note a challenging 50 mile as a minimum level of ability. The event is run by a non profit and proceeds go to local Search and Rescue and military veteran support groups. Refunds are not provided unless the event is cancelled, in which case some funds may be withheld to cover direct expenses. The 2025 edition was cancelled due to Pomas fire closure boundaries affecting the course; organizers indicated they look forward to 2026.
