The hardest part of preparing for something large is not always the work. Sometimes it is not knowing how much work the thing deserves.

Too little training had an obvious risk. Too much training had its own. The correct amount would only become visible after the fact, which made it useless as a planning tool.

Whitney was a dose problem.

People who have summited Whitney successfully have told me I did not need to train to this extent.

Maybe they are right.

They are speaking from the other side of uncertainty. I am still on this side, where enough is not yet a fact.

The thought had not come out of nowhere. I had been endurance training for more than two years. The body had enough history to make the thought less unreasonable.

It is a strange middle place to stand: no longer able to dismiss the thought, not yet able to trust it.

A plan executed alone would have been mine to soften. I could have adjusted it, defended the adjustment, called it recovery, called it prudence, called it better judgment. Some of those reasons might have been true.

This is one of the things a group can do without announcing that it is doing anything at all. It moves a thought out of private custody.

The group plan did not answer whether the work was excessive.

It gave the question fewer chances to become an excuse.

I do not know whether the version I would have designed alone would have looked like this. I suspect it would not have.

January 11, 2026. Whiting Ranch. Whitney had already come up. I had not said yes to it. That morning, a returning member mentioned she had summited last August. I had been training without a fixed goal for two and a half years. A friend had just done the SoCal Six-Pack of Peaks solo; he would not sit on the idea for months. So I asked him to do it together.

By late June the plan we devised had acquired a record. It had opened on January 24, at 7:04 a.m.: [Altitude Series] Bedford Peak - Endurance | NSC. 7.18 miles. 2,073 feet of gain.

Bedford. San Mateo. Tenaja Falls. Bald Peak. Cucamonga. Baden-Powell. Ontario and Bighorn. Baldy ×2. San Bernardino. San Jacinto ×2. San Gorgonio ×2.

Together, they had become 224.36 miles, 60,889 feet of gain, and 81 hours and 43 minutes of moving time.

It had taken weekends, recovery, sleep, food, weather, schedule, fatigue, and the ordinary resistance of beginning again after the last effort had already been paid for.

This is what the private plan would have had to survive.

Mid-June. San Jacinto via Marion Mountain had been the hardest climb of the sequence. San Gorgonio came seven days later. The blood was drawn two days after that, at a routine physical, and came back with one liver enzyme above range. The nurse practitioner reviewing it asked the standard questions. Tylenol? Alcohol the night before? New medications, new supplements?

None of those. I explained the training instead. Months of climbing on top of climbing.

The one that was elevated is not only a liver enzyme. Muscle releases it too, under sustained strain. It climbs in endurance athletes and, in the studies, settles once the effort stops.

I already knew I wasn't recovered when the blood was drawn. The result confirmed it.

She agreed with the plan: retest after the training is done, pursue it further if anything is still out of range. The full panel comes after Whitney, once there's been enough rest to mean something.

The week of July 4 there was no scheduled NSC altitude route. I had penciled in an extra elevation hike of my own to fill it, pending recovery. The bloodwork took it out. What I kept was local: Crystal Cove, 10.75 miles at sea level, with the Sunday group I had not seen since the training moved to Saturdays. They knew about Whitney. The send-off was more than I expected.

The ledger is still open.

Vivian Creek is ahead, the third pass at San Gorgonio. Another 18.5 miles. Another 5,500 feet of gain. The last climb before the climb.

Enough is still not a fact.

But it is no longer a question I can revise in private.
