Sore Legs After a Turkey Trot? A Tennis Pro's Guide to Your Thanksgiving 5K

Every year a few of my tennis players sign up for the Turkey Trot. Most of them haven't run more than the length of a court since the last one. They show up the following week walking down the clubhouse stairs sideways, holding the rail, and tell me their calves are made of concrete. "It was only a 5K," they say. "I play two hours of doubles. How is three miles worse?"

It's worse because running and tennis load your legs in different ways, and a 5K is about 30 minutes of the same motion, thousands of times, usually on pavement, usually faster than you meant to go because the whole town is running with you. I've taught tennis for more than 20 years and run a few of these myself. Here's what I tell my players about getting through a Thanksgiving 5K without spending the long weekend hobbling around the kitchen.

Why a 5K leaves you so sore

On a tennis court you sprint, stop, split-step and walk back to the baseline. You get a short rest every 10 seconds. In a 5K you don't. A typical runner takes somewhere around 1,500 steps per mile, so a 5K is roughly 4,500 landings on each leg with no break. Each landing puts a load of a few times your body weight through your feet, calves, shins and knees.

The soreness usually shows up in a few places:

  • Calves. The number one complaint. Your calves catch you on every step, and tennis players who run up on their toes get it worst.
  • Quads and the fronts of the knees. Downhills are the culprit. Running downhill makes the quads brake on every step, and that braking work is what leaves you sore two days later.
  • Hips and glutes. They keep your pelvis level on every stride. If you sit all week, they're not used to it.
  • Feet and the front of the shins. Hard pavement, old shoes and a pace that's faster than your legs are ready for all add up here.
  • Lower back. Usually from tightness in the hips, or from standing around in the cold at the start corral and then going hard.

That stiff, achy feeling that peaks a day or two after the race is normal muscle soreness from doing more than your legs are used to. It's not a sign you did anything wrong. It's a sign you did something new.

The mistakes I see every year

Going out too fast. The gun goes off, everybody is excited, there's a guy in a turkey costume passing you, and you run the first mile a minute faster than you planned. Your legs pay for that mile for the next 2 miles and the next 3 days.

No training at all. Signing up in October and running for the first time on Thanksgiving morning. Two weeks is not enough to get in shape, but it's plenty to get your legs used to running so race day isn't a shock.

The wrong shoes. Tennis shoes are built for side-to-side movement and a lot of support. Running shoes are built for forward motion and cushioning. Running three miles in court shoes, or in running shoes with 600 miles on them, makes everything below the knee work harder.

Standing around cold, then racing. Thanksgiving morning is often in the 30s. People stand in the corral for 20 minutes, then sprint off with cold, stiff legs.

A two-week plan if you're starting now

If the race is about two weeks out, this is enough to take the edge off:

  • Run 3 or 4 times a week, short and easy. 15 to 25 minutes at a pace where you could hold a conversation. Walk breaks are fine. The goal is to teach your legs the motion, not to get fast.
  • Do one run of about 2 miles around a week before the race, at an easy pace, so you know what the distance feels like.
  • Include a gentle hill or two if your race course has them, so the downhill braking isn't brand new on race day.
  • Take it easy the last 2 days. A short walk or a very easy 10-minute jog. Don't try to cram in fitness the day before.
  • Keep playing tennis or pickleball if you already do. Just don't stack a long match and a run on the same day this close to the race.

7 things to do on race day

  1. Warm up for 10 minutes. Walk briskly for 5 minutes, then 5 minutes of leg swings, walking lunges, calf raises and a few easy jogs of 30 seconds. Same idea as hitting mini-tennis before a match.
  2. Dress for mile two, not the start line. Wear a throwaway layer or an old sweatshirt in the corral, and keep your legs warm until the start.
  3. Start slower than you want to. Run the first mile at a pace that feels almost too easy. If you feel good after mile two, pick it up then.
  4. Shorten your stride on the downhills. Quick, short steps and stay tall. Long, braking steps downhill are what wreck your quads.
  5. Land under your body, not out in front. Think quick feet, like a split-step, instead of reaching with your heel.
  6. Walk if you need to. Nobody remembers your time. Plenty of people walk the whole thing, and walking breaks are a smart way to finish feeling good.
  7. Keep walking for 10 minutes after you finish. Don't stop at the line and stand still. Grab your water and keep moving while your heart rate comes down.

After the race (and before the big meal)

This is the same short routine I give my tennis players after a match:

  • Stretch while you're still warm. 30 seconds each: calves against a wall, a standing quad stretch, a hip flexor stretch, and a hamstring stretch with your heel on a step.
  • Drink water and eat something within an hour or so. A Thanksgiving 5K is one of the few races where nobody has to remind you to eat afterwards.
  • Don't spend the whole day sitting. Help carry dishes, take a walk after the meal, play a little backyard football if you're up for it. Gentle movement is your friend.
  • Get some sleep. Your legs recover overnight.
  • The next day, go for an easy walk. 20 minutes. Stiff legs loosen up faster when you move them.

My full version is the free 5-minute recovery routine. It works just as well after a race.

What I use for the soreness

I'm biased here: I make a pain relief cream, so take this for what it's worth. Active 10 uses menthol, capsaicin and magnesium. It's for the temporary relief of minor aches and pains of muscles and joints associated with simple backache, arthritis, strains, bruises and sprains. That covers the "my calves and quads are killing me after the Turkey Trot" kind of soreness most runners mean.

  • Rub a small amount into the sore calves, quads or lower back, then wash your hands well before you start cooking or touch your eyes.
  • Don't use it on broken or irritated skin, don't wrap the area tightly, and don't use it with a heating pad. Skip the hot bath right after you put it on.
  • The roll-on is handy for the lower back and keeps your hands clean, which matters when you're on stuffing duty.

Always read the label for directions and warnings before you use it.

When to stop and see a doctor

General soreness that peaks in a day or two and fades within the week is normal. These aren't:

  • A sharp pain during the race that makes you limp or stop.
  • Pain in one specific spot on a bone, especially in the shin or foot, that hurts more when you press on it.
  • Swelling, or a knee or ankle that doesn't bend or take weight normally.
  • Calf pain with swelling, warmth or redness in one leg, especially after a long car ride or flight to see family. Get that checked right away.
  • Back pain that runs down your leg, or numbness or tingling.
  • Soreness that isn't better after about a week, or keeps getting worse.

If you have any of those, stop running and get it checked by a doctor or physical therapist.

The short version

Use the next two weeks to run a few short, easy times. Wear running shoes. On race day, warm up for 10 minutes, stay warm in the corral, start slower than you want to, take short steps downhill, and walk when you need to. Afterwards, keep moving, stretch, eat, sleep, and take a walk the next day. You'll be sore, but you'll be walking down the stairs forwards by the weekend, and you'll be ready for your next match.

See you out there, and happy Thanksgiving.
