A resolute Cinderford came from behind to seal promotion to National One following a battling victory over Bury St Edmunds.
The Foresters fought back to clinch the National Two South title after racking up 28 wins from their 29 matches played this season.
While the top two is all done and dusted for another year in this division, the fight for survival is once again going to the final day of the season after another dramatic weekend.
London Irish Wild Geese are nearly home and dry after a crucial win at Henley Hawks, but Barnstaple have dropped into the bottom three after their defeat to Worthing Raiders.
Old Redcliffians are also still not safe as they were beaten by rivals Wimbledon meaning the Dons still have a chance to avoid the drop against all the odds.
Elsewhere across National Two South, Canterbury stunned second placed Chinnor, Redingensians secured third spot, Tonbridge Juddians thrashed Taunton Titians and Redruth overcame Broadstreet.

A first half try from Nathan Taylor gave Cinderford the perfect start, but the scores were level at the interval as Max Kohler scooted over for Bury.
The hosts looked set to spoil Cinderford’s party when Will Scholes and Liam McBride both crossed to leave the visitors trailing by14 points.

Tom Nicoll, Watson and McHugh added more tries for Tonbridge Juddians after the break and although Connor Banks and Aron Struminski (2) both scored for the Titians, it was too little too late.
Redruth 36-24 Broadstreet
Redruth have finished the National Two South season in fifth place after beating relegated Broadstreet at the Recreation Ground in Round 29.
Once again, the Reds produced an excellent home performance and it was the perfect way to bid farewell to the departing Chris Fuca, Kyle Marriott and Sam Parsons.

Christopher Zutic, James Moreton, Chris Idhern and Harry Hudson were Broadstreet’s try scorers.

Henley Hawks 19-36 London Irish Wild Geese
London Irish Wild Geese are on the cusp of securing their place in National Two South for next season after a crucial win away at Henley Hawks.
Having led 12-0 after touchdowns by Zaki Chamnaoui and George Owen, the visitors were pegged back to just a five-point advantage when Will Janes dotted down.
The home side went in front after half-time as Xavier Andre and Janes both touched down, but quick fire scores from Sean Cunningham and Owen put Wild Geese back in front.
And further tries from Scott Moore and Alex Seers settled it for the visitors who are now five points clear of the drop zone while Henley’s wretched run of form continues.
Wimbledon 55-17 Old Redcliffians
Old Redcliffians missed the chance to confirm their safety in National Two South as they were well beaten by a Wimbledon side that are still fighting for survival.

What a day of rugby yesterday at Barham Road. What scenes of jubilation and relief. Another week to fight for our season. With top of the table done and dusted, only 2 games matter in this league now. The Dons vs @BarnstapleRFC and @RedruthRugby vs @OldRedsRFC#dontstopbelieving
