Couch to 5 K - double up?

[DoubleCouch]

I dont feel exhausted after doing the 'run' on the day? So did it twice *missing out the 2nd warm up and first cool down...

Has anyone here done this before?
Any hints?

Don’t do it. The whole point of C25K is that you shouldn’t feel exhausted after a run. It is deliberately designed so that you can gradually build up the time without stressing your body too much so you prevent injury.

Just start on a week that suits you, surely? If you know week 1 is too easy, start on week 3. If that's easy make your second run week 4. Once u get to a week that challenges you, start doing it "properly". It is couch to 5k, so the baseline might be too slow for those who do a lot of other sport.

I dont do anything else, I am the worlds proper couch potato

I want to build up my endurance, and today I did 4.5km on the treadmill

Follow the plan. Tiredness can be cumulative and doing too much on a body that's not used to it can turn into overuse injury a few weeks later.

The plan changes gear in weeks 5-6 as the blocks of running increase and time on feet goes up ready for building the 25+min runs in weeks 7-9.

As an experienced runner, there's been times when I've returned to C25k after short breaks or niggles and I've fast-tracked through the early weeks, but stayed in the order of the plan doing one run of each length, but I already have the long term stamina.

You are clearly not a couch potato! Or your baseline fitness is not bad at all

Yeah, just trust the program, and follow it properly.

I'm sometimes tired when I do one of the runs, and sometimes not. It's a marathon, not a sprint 🙂.

Thanks all
