Ten-man Wrexham missed the chance to go second and crank up the pressure on their title rivals after twice squandering the lead against struggling Tamworth.
Brett Ormerod continued his purple patch with the 26th minute opener but the lead lasted barely three minutes as Connor Gudger headed the Lambs level via a free header.
Wrexham overcame the extremely harsh 52nd dismissal of captain Dean Keates - sent off after picking up a questionable second yellow card - and regained the lead through Danny Wright’s 74th minute tap-in.
However, Scott Barrow levelled five minutes from time with a stunning free-kick.
A win would have moved Wrexham up to second as the games involving Grimsby, Newport County and Luton Town all fell victim to the weather. However, the Lambs belied their lowly position with the sort of gutsy display that should secure them another season in non-league’s top flight.
Reds boss Andy Morrell made two changes to the side that defeated Telford so convincingly on Boxing Day. Neil Ashton came back in after serving a one game suspension whilst Nick Rushton replaced Adrian Cieslewicz">Adrian Cieslewicz after the Pole picked up a injury early in the previous game.
Early half chances fell to Joe Clarke and Brett Ormerod as Wrexham started with gusto. Martin Riley watched his shot cleared off the line as the Lambs failed to clear a corner.
And despite their early dominance Wrexham almost paid a price for backing off Tommy Wright, his shot shaving the post with Joslain Mayebi at full stretch.
The Wrexham keeper was equal to Peter Till’s low-drive, tipping it around the post after the Lambs attacker was allowed to cut in from the left.
Wrexham finally made the breakthrough in the 26th minute. After Ashton’s 25 yard pile-driver had left the cross-bar a gibbering wreck the ball fell to Rushton. His shot was deflected into the path of Ormerod and he made no mistake from five yards.
Instead of building on their lead, Wrexham suddenly found themselves under pressure and the Racecourse was stunned into silence when Connor Gudger headed in the leveller just minutes later. He was all alone at the near post and his header flashed past an exposed Mayebi.
Wrexham enjoyed the lion’s share of possession for the remainder of the half but lacked ideas up front.
The second half was just seven minutes old when referee Anthony Backhouse took centre stage. Despite Reds skipper Keates winning the ball cleanly in a tackle on Till the referee deemed it a yellow card offence. Having been booked in the first half a perplexed Keates was given his marching orders and handed the armband to Ashton as he begrudgingly headed down the tunnel.
After the dust had settled Mayebi did well to smother Scott Barrow’s long-range drive on an increasingly bobbly surface before Ormerod beat the ground in frustration after the ball eluded him from Danny Wright’s deflected shot.
In the 68th minute Wrexham should have regained the lead. Wright headed against the bar from a corner and Clarke put his follow up shot the wrong side of the post from eight yards.
Six minutes later and the lead was restored. Ormerod picked out Wright in space in the box and the big striker took one touch before almost walking the ball into the goal without a Lambs defender in sight.
The visitors struck back immediately, forcing successive corners and asking questions of Wrexham’s nervy defence.
With five minutes left Clarke hacked down Wright and Barrow smashed his low free-kick into the net from 25 yards.
Either side could have won it in added time - Tommy Wright went perilously close with an overhead kick before Declan Walker wasted a decent opportunity with a free-kick in the last play of an end-to-end encounter.
