As usual the number of centuries ramps up in late spring and early summer. Although several events do not have their 2026 information out yet, they are very likely to be offered as long as the clubs have volunteers willing to run the event. That is increasingly an issue. But so far only the Santa Cruz Mountain Challenge, normally in July, seems to have gone on hiatus. Unlike last year when registration fees ticked up yet again, fees this year seem to be roughly stable, which is surprising because insurance costs are continuing to go up. Be grateful you’re paying ‘only’ $100.
