Forest Park is 5,100 acres and the descents are the part that hurts

Forest Park is more than five thousand acres of forested trail, inside the city, reachable on a weekday evening. Very few cities can say that, and it means a lot of Portlanders do real hill mileage without ever calling it training.

The soreness that arrives two days later is almost never from the climbing.

Going down is braking, over and over

Climbing is your muscles shortening under load, which is the thing they are built for. Descending is the opposite: your quads lengthening while resisting, again and again, for as long as the descent lasts. That is the kind of work that produces soreness which peaks on day two rather than day one, and it is why a walk downhill can wreck you more than the climb up did.

On a long Wildwood descent that is thousands of repetitions with a pack on.

• Shorten your stride going down rather than reaching. Long downhill steps are the ones that hurt.
• Let your knees stay soft. Locked legs pass the load straight up into your back.
• If you use poles, use them on the way down, not just on the way up.

Wet roots change everything

For much of the year the trail is wet and the footing is unreliable. Every small slip is a correction your back makes without asking you, and a couple of hours of small corrections adds up to a genuinely tired lower back. That is not an injury, it is a workload, but it explains why a wet hike feels harder than the same dry one.

The day after

Walk on it. The instinct after a big descent is to sit still, and that is what makes day two worse. Gentle flat walking on the following day does more than rest does.

When it is worth talking to somebody

Two days of quad and lower back soreness that fades by midweek is exactly what should happen. Worth a conversation with a qualified provider: pain that is sharp rather than achy, anything that travels down a leg, a knee or ankle that is still swollen after a few days, or anything not improving at all by the end of the week.
