Club Rugby on Six Nations Weekends: Upsets, Home Wins and Points
When the Six Nations is on, club rugby gets tighter rather than wilder. Favourites slip a little, blowouts thin out, and home advantage barely moves.

- Question
- When club league games are played on the same weekend as Six Nations or November Tests, do favourites, home sides and totals behave differently?
- Sample
- 2,482 Top 14, Premiership, URC and Pro D2 matches, January 2022 to August 2026
- Favourites won on Six Nations Test weekends63.8%
- Model expected on those weekends65.5%
- Favourites won on Six Nations fallow weekends70.8%
- Six Nations-weekend games won by 21+21.4%
Every February and March the club calendar plays on while the best players sit in Test camps. Bettors tend to assume that depleted squads mean chaos: upsets, ragged defences, big scores. I wanted to test that against 2,482 Top 14, Premiership, URC and Pro D2 matches, split by what was happening on the international stage that weekend.
The headline answer is that Test weekends do not produce chaos so much as compression. Favourites won 63.8% on Six Nations Test weekends against 65.5% expected, and only 21.4% of those games ended in a 21-point-plus margin. That second figure is the one I keep returning to on my rugby union predictions page during the championship window.
Window 1Favourites slip on Test weekends, thrive in fallow ones
This chart compares what a results-only rating model expected favourites to win with what they actually won, across four kinds of weekend. On Six Nations Test weekends the favourite won 63.8% of 116 games against 65.5% expected. On November Test weekends it was 64.9% against 66.8%, and with no Tests at all 66.4% against 67.6%.
The odd one out is the fallow weekend, when the Six Nations takes a break. Favourites won 70.8% there against 68.4% expected, the only window where they beat the model. My reading is that clubs get some internationals back, or at least have settled, rested squads, and the stronger side's depth shows.

| Model expected | Actually won | 95% range | |
|---|---|---|---|

| Six Nations fallow weekend (137 games) | 68.4% | 70.8% | ยฑ7.6 |
| November Test weekend (111 games) | 66.8% | 64.9% | ยฑ8.9 |
| No Tests that weekend (1,825 games) | 67.6% | 66.4% | ยฑ2.2 |
Be honest about the error bars, though. The Test-weekend range is ยฑ8.7 on a sample that small, so the shortfall is a lean, not a verdict. I treat it as a reason to be less trusting of short-priced favourites, not a reason to oppose them.
Window 2Six Nations weekends squeeze out the big blowouts
This is where the calendar effect is clearest. On Six Nations Test weekends only 21.4% of club games were won by 21 or more, against 28.7% on fallow weekends and 31.5% on November Test weekends. The middle band does the work instead: 43.4% of Test-weekend games finished with an 8-20 margin.
For handicap bettors, that matters more than the outright market. When both packs are missing front-rowers and the lineout callers are in camp, neither side tends to have the set-piece platform to run away with a game. You get grinding, territory-based rugby where the stronger side wins but rarely by four scores.

| Draw or 1-7 | 8-20 | 21+ | |
|---|---|---|---|
| Six Nations Test weekend | 35.2% | 43.4% | 21.4% |
| Six Nations fallow weekend | 42.5% | 28.7% | 28.7% |
| November Test weekend | 37.8% | 30.6% | 31.5% |
| No Tests that weekend | 39.3% | 33.5% | 27.1% |
The surprise is that tight finishes do not rise to match. Games within 7 points or drawn made up 35.2% on Test weekends, below the 42.5% on fallow weekends and 39.3% with no Tests. So the shape is not coin-flips; it is comfortable but modest wins.
Window 3Home advantage holds steady whatever the Test calendar
If any edge were going to wobble on Test weekends, I expected it to be home advantage, given travelling squads and patched-up line-ups. It barely shifts. Home sides won 69.0% on Six Nations Test weekends, 67.1% on fallow weekends, 69.1% on November Test weekends and 68.6% with no Tests.

| Top 14, Premiership, URC and Pro D2, home ground only | |
|---|---|
| Six Nations Test weekend | 69.0% |
| Six Nations fallow weekend | 67.1% |
| November Test weekend | 69.1% |
| No Tests that weekend | 68.6% |
The fallow-weekend dip is small, and it sits alongside favourites doing better, which suggests the better side wins regardless of venue that week. I would not build anything around home sides purely because of the calendar.
Window 4Totals dip slightly when the internationals are away
The table pulls it together. Matches averaged 49.6 points on Six Nations Test weekends and on November Test weekends, against 51.2 on weekends with no Tests and 50.9 on fallow weekends. Games reaching 50 or more points ran at 50.0% on both Six Nations windows, 48.6% in November and 52.3% otherwise.
Fair home-win odds tell the same steady story: 1.45 on Six Nations Test weekends, 1.49 on fallow weekends and 1.46 when no Tests are played. The real caveat is composition. The Top 14 and Pro D2 keep playing through Test weekends while the URC and Premiership often pause, so these windows mix leagues in different proportions, and the records hold results rather than prices.
| Weekend | Games | Home win | Fair odds | Avg total | 50+ points |
|---|---|---|---|---|---|
| Six Nations Test weekend | 182 | 69.0% | 1.45 | 49.6 | 50.0% |
| Six Nations fallow weekend | 174 | 67.1% | 1.49 | 50.9 | 50.0% |
| November Test weekend | 111 | 69.1% | 1.45 | 49.6 | 48.6% |
| No Tests that weekend | 2,015 | 68.6% | 1.46 | 51.2 | 52.3% |
Best window
- Shade the big handicaps
Only 21.4% of Six Nations Test-weekend games were won by 21+, so I am wary of laying large lines when packs are depleted. The 8-20 band, at 43.4%, is where those games tended to land.
- Trust favourites on fallow weekends
Fallow weekends were the only window where favourites beat the model, winning 70.8% against 68.4% expected. That is when restored squads seem to let quality tell.
- Lean slightly under on totals
Test weekends averaged 49.6 points against 51.2 with no Tests. It is a modest gap, so I use it as a tiebreaker on totals rather than a reason to bet.
Questions bettors ask
Do favourites lose more in club rugby during the Six Nations?
Slightly. Favourites won 63.8% on Six Nations Test weekends against 65.5% expected, but the ยฑ8.7 range means the shortfall is a lean rather than a firm pattern.
Is home advantage weaker on Six Nations weekends?
No. Home sides won 69.0% on Six Nations Test weekends, almost identical to the 68.6% on weekends with no Tests, giving fair odds of 1.45 against 1.46.
Are club games lower scoring during the Six Nations?
A little. Matches averaged 49.6 points on Six Nations Test weekends against 51.2 when no Tests were played, and 50.0% reached 50 or more points.
