Tuesday's trip to Chorley was followed by Wednesday night in Kendal for the Blues - and, yes, it was still sweltering!
The game was an opportunity to raise funds for George Melling, who turned up to watch part of the second half accompanied by a huge round of applause.
United had the first sight of the target of the encounter when Toure was hacked to the floor as he set off on a run. Dixon took charge of the free kick but his inswinging cross was cleared as far as Charters. A scramble followed a blocked shot from the edge of the box and the hosts worked their way clear.
Good work from Mellish saw him regain possession tight by the corner flag as the away side came again. He fed it to Mampala, but the trialist sent his low effort straight at the keeper.
The home side were presented with an opening on 12 minutes when the ball bobbled off the surface in front of Devine. That allowed the winger to sprint free but he dragged his effort past the post from the edge of the box.
Trialist Manny Mampala was alert at the other end when a loose pass allowed him to stride on. He had just one thing in mind but his low cruncher was too close to the stopper.
A second late and high tackle from the Kendal number 6 saw him go in the book, and Toure tested the keeper with a rasping free kick after the telling off had been given. The parry had Charters interested but the door was closed and the ball hooked clear.
Simons was in action on 20 minutes when a long range attempt skipped up in front of him. He went full length to push it away.
The left wing was a productive area for the visitors with Mampala and Toure on patrol, and the former was almost through again when he bent his run from deep. He was tackled just as he shaped to pull the trigger.
Carlisle took the lead on 23 minutes with another slicing move down the left. Bell and Charters opened things up and Jon Mellish cushioned a beauty of a volley past the keeper as he arrived to meet the delivery just in the nick of time.
United almost doubled their lead moments later when Dixon whipped a free kick in from the right flank. The keeper saw it late but he recovered well to push it two-handed onto the bar.
Kendal surged forward and Simons had to scamper off his line to tidy things up as the ball somehow squirmed through into the danger area.
The visitors extended their lead just past the half hour when a deep corner was kept alive. It eventually came back to Morgan Feeney, who had moved intelligently into space. A measured close-range header left the keeper with no chance.
And it became a three-goal cushion when Mampala was dragged back having ridden a challenge. Josh Dixon rattled the free kick towards the bottom corner and he scored ten out of ten for accuracy when he bulged the net.
The action stayed in midfield at the start of the second period, but Toure caused havoc when he stepped over the ball before crossing. Kendal cleared, but Bell was onto the loose pieces in a flash. He jinked through two challenges before sending Fishburn into the box. The big forward's first time shot was stopped at source.
Carlisle bagged goal number four on the night when Toure pulled wide. It came his way, and an instinctive cross was met by Fishburn. His volley was smothered, but Mampala was there to finish things off.
Charters thundered one just wide as United pressed high, but Simons was needed at the other end when a flick left a man free. The keeper spread himself to make an excellent save.
Unusual for a friendly - the Kendal number 17 was sent off (having already been shown a yellow) following an altercation in the visiting area. It's very possible that it was a straight red card.
The away side put the incident behind them and Toure went close when he wriggled into the area. His toe poke was palmed up into the air by the keeper, and the dipping ball was then cleared off the line.
10-man Kendal crashed a blistering shot against the woodwork, and Simons had to tip one wide when the home side came again in what was a good spell for Kendal.
Second-year scholar Sam Fishburn got his goal when he controlled a flighted pass from Bell. He kept his cool as he took two touches before stroking it home from nine-yards out.
Bell then sent Mampala clear as he found his passing boots. The striker had just the stopper to beat, but it was the man with the gloves who came out on top this time.
A sixth was added with just over five minutes left to play when Mampala took a fizzed pass with his back to goal. A back heel set Toure through and his finish can only be described as emphatic.
