Autumn is the crowded end of the UK racing calendar. A half in September, a marathon in October, a trail race or a Hyrox in November. Racing often is not the problem. Racing often without a plan for the gaps is what leaves people arriving at their target event flat, sore or nursing a niggle that was avoidable.
The question I get asked every autumn is "how long do I need between races". That is the wrong question. The useful one is what actually needs to recover, how quickly each part of it comes back and what you can do in the gap to help.
Different systems recover at different speeds
A hard race leaves you with several separate problems, and they do not resolve on the same clock.
-
FUEL: Muscle glycogen is emptied by anything over about 90 minutes at effort. Eat properly and it refills inside 24 to 48 hours.
-
FLUID AND ELECTROLYTES: Usually back to normal within a day if you drink to thirst and take some salt with food.
-
MUSCLE DAMAGE: The eccentric loading of downhill running tears fibres. Soreness peaks somewhere between 24 and 72 hours, and full repair takes most of a week.
-
CONNECTIVE TISSUE: Tendons and fascia adapt far more slowly than muscle. This is the slow one, measured in weeks, and it is the one that quietly decides whether your second race goes well.
-
THE HEAD: Racing hard costs you something you cannot see on a watch. Two races close together are fine. Four in six weeks and most people stop being willing to hurt.
So fuel and fluid are sorted in a couple of days, muscle is mostly repaired inside a week and tendon load tolerance is what caps how often you can race well.
The first two hours set the tone
What you do immediately after crossing the line matters more than anything you do on the Wednesday. Keep moving for five or ten minutes rather than sitting down in the finish funnel. Get something with carbohydrate and protein in within the hour, even if you do not fancy it. Get out of wet kit and into something dry and warm, because standing around cold in a British October is how a sore calf becomes a strained one.
Then put compression on. Not as a magic trick, but because it is the easiest useful thing available at a point when you will not do anything else sensible.
What compression does between races, and what it does not
Be clear about the evidence. Graduated compression has reasonable support for recovery outcomes: lower perceived soreness in the days after hard efforts, and reduced swelling in the lower leg. The support for it making you faster is mixed and modest at best. I would not tell any athlete to expect a personal best because of what they are wearing.
Where it earns its place is the gap between races. If you feel less beaten up on the Tuesday, you run better on the Wednesday, and the second race starts from a better place.
-
RACE SOCKS: 25-30 mmHg firm graduated compression, worn for two to four hours after finishing and again on travel days. This is the highest pressure in the SA1NT LAYERS range and the one most people notice.
-
TIGHTS AND SHORTS: 15-20 mmHg medical grade graduated compression in a 225 GSM circular knit. Comfortable enough to wear all evening, which matters more than peak pressure because adherence is the whole game.
-
CALF GUARDS: 15-20 mmHg at 230 GSM. Useful if your calves and Achilles take the brunt and you want support without a full tight.
Choosing the gap
Rough guidance, assuming you raced the first one properly rather than jogging it.
-
PARKRUN TO 10K: Seven days is plenty. These are short enough that fuel and muscle damage are the only real costs.
-
HALF MARATHON: Two weeks before you race hard again. You can run a half as a paced effort a week later, but do not expect to compete.
-
MARATHON OR ULTRA: Four to six weeks before another hard race, longer if you want the second to go well. Tendons are the limit here, not legs.
-
HYROX: Two to three weeks. The sled and lunge work loads tissue differently from running, so a Hyrox followed by a road race often sits better than two of the same.
Running the week between two races
Assume race Sunday and race again a fortnight later. The first week is not a training week, it is a repair week. Two or three very easy runs, nothing over 40 minutes, no structured session before Thursday at the earliest. Walk more than usual. Sleep is doing more work than any protocol you could buy.
Week two is where you put a little sharpness back. One short session with some race pace in it early in the week, easy running either side, then a normal pre-race couple of days. You are not building fitness in that fortnight. You are trying to arrive fresh with the fitness you already had. Most people get this backwards and squeeze in a hard session out of guilt about the easy week.
If you want the detail on the final stretch, the approach in Marathon Race Week: How to Use Compression in the Final Ten Days transfers straight across. The post-race side is covered in more depth in How to Use Compression Gear for Post-Workout Recovery.
When to drop the second race
Some signals are worth respecting rather than negotiating with.
-
LOCALISED PAIN: Soreness that is spread across a muscle group settles. Pain you can point at with one finger, particularly around a tendon, does not settle just because there is a start line on Sunday.
-
SORENESS PAST DAY FIVE: If you are still stiff going down stairs on the Friday after a Sunday race, the repair is not done.
-
A HEART RATE THAT WILL NOT DROP: Easy pace costing you ten beats more than normal for several days running usually means you are not recovered.
-
NO DESIRE TO RACE: Not nerves, which are normal. Actual indifference. That is a real signal and it is worth listening to.
Dropping a B race to protect an A race is not weakness. It is the whole point of calling one of them an A race.
What goes in the bag
The kit that earns its place is what you will actually use on the drive home and the evening after.
-
DRY LAYERS: A full change including socks. Cold and wet after a race is where most autumn niggles start.
-
COMPRESSION FOR AFTER: Whatever you will genuinely put on in a car park. Socks are the easiest because you can change into them sitting down.
-
A NOTE ON YOUR PHONE: What hurt, what went well, what you would change. You will not remember by the next race and the pattern across an autumn is more useful than any single result.
Race often if you enjoy racing. Just be honest about which one you actually care about, and treat the gaps as part of the plan rather than dead time. If you want the recovery side handled properly, the SA1NT LAYERS Compression Race Socks at 25-30 mmHg are the simplest place to start, and the compression range covers the rest.
